2020 ECOLOGY REVIEW: Interactions and Flow of Energy/Matter

Front

What is biological magnification?

Back

Biological magnification refers to the increasing concentration of toxins in the tissues of organisms at each successive level of the food chain.

Front

What is a trophic level?

Back

A trophic level is a position in a food chain or food web, representing the flow of energy and matter through an ecosystem.

Front

What is a density-independent limiting factor?

Back

A density-independent limiting factor is a factor that affects population size regardless of the population's density, such as temperature or natural disasters.

Front

What is a density-dependent limiting factor?

Back

A density-dependent limiting factor is a factor that affects population size in relation to the population's density, such as competition or disease.

Front

What role do decomposers play in an ecosystem?

Back

Decomposers break down dead organic matter, recycling nutrients back into the soil and making them available for producers.

Front

What is the difference between producers and consumers?

Back

Producers are organisms that create their own food through photosynthesis (e.g., plants), while consumers are organisms that obtain energy by eating other organisms.

Front

What is the carbon cycle?

Back

The carbon cycle is the process by which carbon is exchanged between the atmosphere, land, water, and living organisms.

Front

How does deforestation impact carbon dioxide levels?

Back

Deforestation reduces the number of trees available to absorb carbon dioxide, leading to increased levels of CO2 in the atmosphere.

Front

What is 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 a food web?

Back

A food web is a complex network of interconnected food chains in an ecosystem, showing how different organisms are related through feeding relationships.
