Flashcard - Matter and Energy in Ecosystems

Front

What is the role of autotrophs in an ecosystem?

Back

Autotrophs capture energy from the sun and convert it into chemical energy through photosynthesis.

Front

What are the reactants in the photosynthesis equation?

Back

The reactants in the photosynthesis equation are water and carbon dioxide.

Front

Does energy flow from one trophic level to the next?

Back

True, energy flows from one trophic level to the next in an ecosystem.

Front

What is the role of decomposers in the ecosystem?

Back

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

Front

What is the primary source of energy for most ecosystems?

Back

The primary source of energy for most ecosystems is solar energy.

Front

Define autotrophs.

Back

Autotrophs are organisms that produce their own food using sunlight or chemical energy.

Front

What is photosynthesis?

Back

Photosynthesis is the process by which autotrophs convert light energy into chemical energy in the form of glucose.

Front

What are trophic levels?

Back

Trophic levels are the hierarchical levels in an ecosystem, representing the flow of energy and nutrients from producers to consumers.

Front

What is a food chain?

Back

A food chain is a linear sequence of organisms through which nutrients and energy pass as one organism eats another.

Front

What is a food web?

Back

A food web is a complex network of interconnected food chains in an ecosystem.
