ES Jones Final Exam practice

Front

Why are energy pyramids important for studying ecological balance?

Back

They illustrate the impact of human activities on ecosystems.

Front

What happens to energy as it moves up the trophic levels in an energy pyramid?

Back

It decreases due to metabolic processes and energy loss.

Front

Which type of irrigation has the most efficient water usage?

Back

Drip irrigation.

Front

What is a key reason for energy loss between trophic levels?

Back

Energy is used for metabolic processes and heat production.

Front

The gas found in the largest concentration in the troposphere is:

Back

Nitrogen gas.

Front

Define an energy pyramid.

Back

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

Front

What is a trophic level?

Back

A specific level in a food chain or food web, representing organisms that share the same function in the ecosystem.

Front

Explain the concept of metabolic processes.

Back

Biochemical reactions in organisms that convert food into energy and support life functions.

Front

What is the significance of producers in an energy pyramid?

Back

Producers, like plants, form the base of the energy pyramid and are essential for energy flow in ecosystems.

Front

Describe the role of consumers in an ecosystem.

Back

Consumers are organisms that obtain energy by feeding on other organisms, playing a crucial role in energy transfer.
