Biodiversity has become an integral piece in the fabric of different cultures. It’s not just about diet; it’s about symbolism and functionality as well.

All life forms have descended from an ancient, shared common ancestor and have changed over time to survive in the environments in which they live.

The history of life recorded by _________ presents compelling evidence of evolution.

Refers to the fraction of phenotype variation that can be attributed to genetic differences, or genetic variance, among individuals in a population.

Mutations to an individual’s DNA may introduce new variation into a population.

“Survival of the fittest” is not “survival of the strongest”.

Any changes in the environment brought on by natural or artificial changes will cause animals to evolve to those changes.

Refers to the formation of new and distinct species in the course of evolution which involves the splitting of a single evolutionary lineage into two or more genetically independent lineages.

It refers to a certain conditions or situations whereby results in the dying out of a species of which plays an important role in the evolution of life because it opens up opportunities for new species to emerge.

It is defined as the number of different species present in an ecosystem and relative abundance of each of those species.

The more diverse ecosystem tends to be more productive.

The greater species richness and productivity makes an ecosystem more sustainable and stable.

The more diverse the ecosystem, greater is the ability to withstand environmental stresses like drought or invasive infestations.

Over-exploitation of natural resources leads to the extinction of many species.

A ____________ is a group of individuals (all members of a single species) who live together in the same habitat and are likely to interbreed and has a unique physical distribution in time and space.

It refers to the number of organisms that an ecosystem can sustainably support in any ecosystems for a particular species may be influenced by many factors, such as the ability to regenerate the food, water, atmosphere, or other necessities that populations need to survive.

It is the type of ecological succession in which organisms colonize an essentially lifeless area.

The first organisms to colonize the rock are called pioneer species.

Secondary succession is usually faster than primary succession because soil and nutrients are already present due to ‘normalization’ by previous pioneer species, and because roots, seeds and other biotic organisms may still be present within the substrate.

It is greatest when all the species present are equally abundant in the area.

Each species plays an important role in an ecosystem. The role that a species plays in its ecosystem is known as its “__________”. Species can be broadly divided into generalist and specialist species.

Species that normally live and thrive in a particular ecosystem.

Populations with two or more variations of particular characteristics are called ____________.

It can arise from gene mutations or from genetic recombination (a normal process in which genetic material is rearranged as a cell is getting ready to divide). These variations often alter gene activity or protein function, which can introduce different traits in an organism.

When the environment changes, the organisms have to adapt quickly or perish.

It is the set of rules by which information encoded within genetic material (DNA or mRNA sequences) is translated into proteins (amino acid sequences) by living cells. Biological decoding is accomplished by the ribosome, which links amino acids in an order specified by mRNA, using transfer RNA (tRNA) molecules to carry amino acids and to read the mRNA three nucleotides at a time.

These are records left by organisms on the rock which may be an imprints that has been preserved for a long period of time.

Genes are factors in the chromosomes of cells that determine hereditary characteristics.

It is the change in the frequency of an existing gene variant in a population due to random sampling of organisms. The alleles in the offspring are a sample of those in the parents, and chance has a role in determining whether a given individual survives and reproduces.

It is the management of nature and of Earth's biodiversity with the aim of protecting species, their habitats, and ecosystems from excessive rates of extinction and the erosion of biotic interactions. It is an interdisciplinary subject drawing on natural and social sciences, and the practice of natural resource management.

It is the ability to exist constantly. In the 21st century, it refers generally to the capacity for Earth's biosphere and human civilization to co-exist. It is also defined as the process of people maintaining change in a homeostasis-balanced environment, in which the exploitation of resources, the direction of investments, the orientation of technological development, and institutional change are all in harmony and enhance both current and future potential to meet human needs and aspirations.

The term used in genetics for the composite observable characteristics or traits of an organism. The term covers the organism's morphology or physical form and structure, its developmental processes, its biochemical and physiological properties, its behavior, and the products of behavior.

The term _________ summarizes the array of resources, physical and biotic factors that are present in an area, such as to support the survival and reproduction of a particular species.

It is the biological variety and variability of life on Earth, typically a measure of variation at the genetic, species, and ecosystem level.

It refers to how close in numbers each species in an environment is. Mathematically it is defined as a diversity index, a measure of biodiversity which quantifies how equal the community is numerically.

An organism—often a microorganism or a plant—that serves as a measure of the environmental conditions that exist in a given locale.

The state or condition of being subject to death; mortal character, nature, or existence.

In population ecology, it is the scientific term for birth rate. Along with mortality rate, natality rate is used to calculate the dynamics of a population. They are the key factors in determining whether a population is increasing, decreasing or staying the same in size.

It is an interaction between organisms or species in which both the organisms or species are harmed. Limited supply of at least one resource used by both can be a factor.

It is the relocation of people from one country in order to permanently live in another. It is the same process as immigration, which is the influx of people from another country.

It is a measure of the number of organisms that make up a population in a defined area. whereby applies to all organisms on Earth, including the plants that make up vast crops, trees of the jungle, animals on the farm, fish in the ocean, and humans on the planet.

It is the maximum reproductive capacity of an organism under optimum environmental conditions.

It is a species that is very likely to become extinct in the near future, either worldwide or in a particular political jurisdiction which may be at risk due to factors such as habitat loss, poaching and invasive species.

It is an introduced organism that negatively alters its new environment. Although their spread can have beneficial aspects, adversely affect the invaded habitats and bioregions, causing ecological, environmental, and/or economic damage.

It is the differential survival and reproduction of individuals due to differences in phenotype. It is a key mechanism of evolution, the change in the heritable traits characteristic of a population over generations.

It is the evolutionary process whereby an organism becomes better able to live in its habitat or habitats which help organisms survive in their ecological niches.

Species that are only found in one area and are especially vulnerable to extinction.

The fundamental unit of evolution.

Fittest organisms can live long enough to reproduce. hence, they have better chances of passing on their genes to offspring.
