What is the role of decomposers in an ecosystem?

Back

Decomposers break down dead organic matter, recycling nutrients back into the ecosystem.

Front

What is dynamic equilibrium in an ecosystem?

Back

Dynamic equilibrium refers to a state where the populations of organisms in an ecosystem remain stable over time due to interactions such as predation and competition.

Front

What are abiotic factors?

Back

Abiotic factors are non-living components of an ecosystem, such as water, sunlight, air, and soil.

How does overfishing contribute to algae overgrowth?

Back

Overfishing reduces the number of organisms that feed on algae, allowing algae populations to grow unchecked.

Front

What is an energy pyramid?

Back

An energy pyramid is a graphical representation of the energy flow in an ecosystem, showing the energy available at each trophic level.

Front

What is the primary producer in an ecosystem?

Back

Primary producers are organisms that produce energy through photosynthesis, such as plants and algae.

Front

What is the difference between primary and secondary consumers?

Back

Primary consumers eat primary producers (herbivores), while secondary consumers eat primary consumers (carnivores or omnivores).

Front

What is the significance of the 10% rule in energy transfer?

Back

The 10% rule states that only about 10% of the energy from one trophic level is transferred to the next level, with the rest lost as heat.

Front

What is the role of competition in ecosystems?

Back

Competition occurs when organisms vie for the same resources, influencing population dynamics and community structure.

Front

What is a food web?

Back

A food web is a complex network of feeding relationships among organisms in an ecosystem, illustrating how energy and nutrients flow.
