Fall 2024 Review Day 5

Front

What is the 10% rule in the context of energy flow in an ecosystem?

Back

Only 10% of energy is transferred from one trophic level to the next.

Front

What is the primary reason for energy loss at each trophic level in an energy pyramid?

Back

Energy is lost as heat during metabolic processes.

Front

What type of symbiosis involves both species benefiting from the relationship?

Back

Mutualism.

Front

What type of symbiosis involves one species benefiting at the expense of another?

Back

Parasitism.

Front

What type of symbiosis involves one species benefiting while the other is neither helped nor harmed?

Back

A relationship where one organism (the predator) kills and eats another organism (the prey).

Front

Define biomass in the context of an ecosystem.

Back

The total mass of living matter within a given area or volume.

Front

What is an energy pyramid?

Back

A graphical representation showing the flow of energy through different trophic levels in an ecosystem.

Front

What happens to energy as it moves up trophic levels?

Back

Energy decreases due to loss as heat and metabolic processes.

Front

What is the role of producers in an ecosystem?

Back

Producers convert solar energy into chemical energy through photosynthesis.
