Ecology EOC Review

Front

What is carrying capacity?

Back

The maximum number of individuals of a species that an environment can support sustainably.

Front

What is the energy transfer efficiency between trophic levels?

Back

Typically, only about 10% of the energy is transferred from one trophic level to the next.

Front

What is an example of a producer in an ecosystem?

Back

Plants, such as lilypads, are producers that convert sunlight into energy through photosynthesis.

Front

What is an owl's role in an ecosystem?

Back

Owls are predators that receive the least amount of energy from the producers compared to other organisms in the food chain.

Front

What is exponential growth in a population?

Back

A growth model where the population size increases rapidly in proportion to the current size, often represented by a J-shaped curve.

Front

What is logistic growth?

Back

A growth model that describes how a population grows rapidly at first and then levels off as it approaches the carrying capacity, represented by an S-shaped curve.

Front

What happens to the carrying capacity if a habitat is destroyed?

Back

The carrying capacity typically decreases due to loss of resources and habitat.

Front

What is a trophic pyramid?

Back

A graphical representation of the energy flow in an ecosystem, showing the different levels of producers, consumers, and decomposers.

Front

What is the primary source of energy for most ecosystems?

Back

The sun is the primary source of energy, which is captured by producers through photosynthesis.

Front

What is a food chain?

Back

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