Ecology flashcard

Front

What process removes carbon from the atmosphere?

Back

Photosynthesis is the process by which plants convert carbon dioxide into glucose and oxygen, effectively removing carbon from the atmosphere.

Front

What is the relationship between a parasite and its host?

Back

In a parasitic relationship, one species benefits (the parasite) while the other is harmed (the host).

Front

What role do decomposers play in an ecosystem?

Back

Decomposers break down dead organic matter, recycling nutrients back into the ecosystem, although they are often not shown in food chains.

Front

What is an example of a biotic factor affecting fish?

Back

Algae growing in the water is a biotic factor that can affect fish populations by providing food or altering oxygen levels.

Front

Is it true that all carbon in existence is continually recycled in the carbon cycle?

Back

True. The carbon cycle describes the continuous movement of carbon among the atmosphere, oceans, soil, and living organisms.

Front

What are producers in an ecosystem?

Back

Producers are organisms, like plants, that create their own food through photosynthesis and serve as a food source for other organisms.

Front

Define a food chain.

Back

A food chain is a linear sequence of organisms through which nutrients and energy pass as one organism eats another.

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, light, and temperature).

Front

What is the significance of biodiversity in an ecosystem?

Back

Biodiversity contributes to ecosystem resilience, productivity, and stability, allowing ecosystems to adapt to changes.

Front

What is an example of a primary consumer?

Back

Primary consumers are herbivores that eat producers; for example, rabbits that eat grass.
