Matter and Energy in Ecosystems Test

Front

What is matter?

Back

Matter is anything that has mass and takes up space. It can exist in different states, such as solid, liquid, and gas.

Front

What is energy?

Back

Energy is the ability to do work or cause change. It exists in various forms, including kinetic, potential, thermal, and chemical energy.

Front

What is an ecosystem?

Back

An ecosystem is a community of living organisms interacting with their environment, including both biotic (living) and abiotic (non-living) components.

Front

What role do producers play in an ecosystem?

Back

Producers, like plants and algae, create their own food through photosynthesis, converting sunlight into energy and forming the base of the food chain.

Front

What is photosynthesis?

Back

Photosynthesis is the process by which green plants and some other organisms use sunlight to synthesize foods with the help of chlorophyll, converting carbon dioxide and water into glucose and oxygen.

Front

What is the carbon cycle?

Back

The carbon cycle is the process by which carbon is exchanged among the atmosphere, land, water, and living organisms, involving processes like photosynthesis, respiration, and decomposition.

Front

What are consumers in an ecosystem?

Back

Consumers are organisms that cannot produce their own food and rely on eating other organisms (plants or animals) for energy.

Front

What is respiration?

Back

Respiration is the process by which living organisms convert glucose and oxygen into energy, releasing carbon dioxide and water as byproducts.

Front

What is a food chain?

Back

A food chain is a linear sequence that shows how energy and nutrients flow from one organism to another in an ecosystem.

Front

What is a food web?

Back

A food web is a complex network of interconnected food chains that illustrates how energy and nutrients are transferred among various organisms in an ecosystem.
