Biology Review Flashcard. Week 6

Front

What is a decomposer?

Back

Decomposers are organisms that break down dead and decaying matter, returning nutrients to the soil.

Front

What is carrying capacity?

Back

Carrying capacity is the maximum number of organisms an area can support for an extended period of time.

Front

What are limiting factors?

Back

Limiting factors are environmental conditions that affect the size of a population in a habitat.

Front

What role do producers play in an ecosystem?

Back

Producers are organisms that create their own food through photosynthesis, forming the base of the food chain.

Front

What is the difference between biotic and abiotic factors?

Back

Biotic factors are living components of an ecosystem (like plants and animals), while abiotic factors are non-living components (like water, sunlight, and temperature).

Front

How do decomposers contribute to the ecosystem?

Back

Decomposers recycle nutrients back into the ecosystem, making them available for producers.

Front

What is an example of a limiting factor in an ecosystem?

Back

Examples of limiting factors include food availability, water supply, and habitat space.

Front

What is the significance of a population's carrying capacity?

Back

The carrying capacity indicates the maximum population size that an environment can sustain, influencing population dynamics.

Front

What is the role of consumers in an ecosystem?

Back

Consumers are organisms that obtain energy by eating other organisms, playing a crucial role in the food web.

Front

What is an example of a decomposer?

Back

Examples of decomposers include fungi, bacteria, and earthworms.
