Matter and Energy in Ecosystems

Front

What are decomposers?

Back

Decomposers are organisms that break down dead or decaying organic material, returning nutrients to the soil. Examples include worms, fungi, and bacteria.

Why do more plants grow in shallow water than in deep water?

Back

More sunlight reaches shallow water, which is essential for photosynthesis, allowing plants to grow better.

Front

What is a primary consumer?

Back

A primary consumer is an organism that eats producers (plants). Examples include herbivores like rabbits and deer.

Front

What is a secondary consumer?

Back

A secondary consumer is an organism that eats primary consumers. Examples include carnivores like snakes and some birds.

Front

What is a tertiary consumer?

Back

A tertiary consumer is an organism that eats secondary consumers. Examples include apex predators like eagles and lions.

Front

What is the role of producers in an ecosystem?

Back

Producers, such as plants, convert sunlight into energy through photosynthesis, forming the base of the food chain.

Front

What is the significance of the carbon cycle in ecosystems?

Back

The carbon cycle is crucial for regulating Earth's climate and providing carbon for living organisms, as it moves carbon through the atmosphere, biosphere, and geosphere.

Front

How do energy and matter flow through an ecosystem?

Back

Energy flows in one direction (from producers to consumers) while matter is recycled through decomposers.

Front

What is an ecosystem?

Back

An ecosystem is a community of living organisms interacting with their physical environment.

Front

What is biodiversity?

Back

Biodiversity refers to the variety of life in a particular habitat or ecosystem, including the number of species and genetic diversity.
