Dynamic Ecosystems

The levels of organization in an environment are:

• Organism, Population, Community, Ecosystem, Biome, Biosphere

• Cell, Tissue, Organ, Organ System, Organism

• Molecule, Cell, Tissue, Organ, Organism

• Atom, Molecule, Cell, Tissue, Organ

How do resources affect population?

• Resources have no effect on population.

• Resources limit the growth of population.

• Resources always increase population.

• Resources decrease population.

How big can populations get?

• Populations can grow indefinitely without any limits.

• Populations can grow until they reach the carrying capacity of their environment.

• Populations can only grow to a certain size before they start to shrink.

• Populations can grow only if there are no predators.

What is the definition of 'Biosphere'?

• The biosphere refers to the study of plant life only.
• The biosphere is the global sum of all ecosystems, where life exists on Earth.
• The biosphere is a type of geological formation.
• The biosphere is a term for the Earth's atmosphere.

What is the definition of 'Population'?

• The total number of individuals of a species in a specific area.
• The genetic diversity within a species.
• The geographical distribution of a species.
• The average age of individuals in a species.

What is the definition of 'Species'?

• A species is a single organism that cannot reproduce.
• A species is a classification of all living things regardless of reproduction.
• A species is a group of organisms that only share physical characteristics.

• A community is a group of people living in isolation.
• A community is a group of individuals sharing common interests or goals.

What is the definition of 'Limiting Factor'?

• A limiting factor is a type of organism that thrives in any environment.
• A limiting factor refers to the maximum size of a population that can be supported.
• A limiting factor is an unlimited resource that promotes growth.
• A limiting factor is a resource or condition that limits the growth or success of an organism or population.

What is the definition of 'Biotic Potential'?

• The maximum reproductive capacity of an organism under ideal conditions.
• The total number of species in an ecosystem.
• The ability of an organism to adapt to its environment.
• The average lifespan of an organism.

What is the definition of 'Carrying Capacity'?

• The maximum population size that an environment can sustain indefinitely.
• The rate at which a population reproduces.
• The amount of resources available in a habitat.
• The total number of species in an ecosystem.
