Semester 1 Review Day 2: Biodiversity and Ecosystems

Front

What is biodiversity?

Back

Biodiversity refers to the variety of life in a particular habitat or ecosystem, including the diversity of species, genetic variation, and ecosystem diversity.

Front

What is gene diversity?

Back

Gene diversity is the total number of genetic characteristics in the genetic makeup of a species, which contributes to the adaptability and survival of the species.

Front

What is an ecosystem?

Back

An ecosystem is a community of living organisms interacting with their physical environment, including both biotic (living) and abiotic (non-living) components.

Front

What is a biome?

Back

A biome is a large geographical biotic unit, a major community of plants and animals with similar life forms and environmental conditions, such as forests, deserts, and grasslands.

Front

What is the biosphere?

Back

The biosphere is the global sum of all ecosystems, representing the zone of life on Earth, where land, water, and the atmosphere interact.

Front

What is a population in ecological terms?

Back

A population is a group of individuals of the same species that live in a specific area and can interbreed.

Front

What is a community in ecology?

Back

A community is a group of different species that live together in one area and interact with each other.

Front

What is the difference between ecosystem diversity and species diversity?

Back

Ecosystem diversity refers to the variety of ecosystems within a given area, while species diversity refers to the variety of species within a particular ecosystem.

Front

What are the three main spheres of the Earth?

Back

The three main spheres are the biosphere (life), hydrosphere (water), and geosphere (land).

Front

What is an example of low gene diversity?

Back

A population where all individuals have the same genetic traits, such as all cats in a litter being red with white spots.
