What is a herbivore?

Back

A herbivore is an organism that primarily eats plants. In a food web, herbivores are the first consumers that obtain energy directly from producers (plants).

What is a decomposer?

Back

A decomposer is an organism that breaks down dead organic material, returning nutrients to the ecosystem. Examples include fungi and bacteria.

Front

What is a food web?

Back

A food web is a complex network of feeding relationships among organisms in an ecosystem, showing how energy flows through different trophic levels.

Front

What is the difference between a food chain and a food web?

Back

A food chain is a linear sequence of organisms through which nutrients and energy pass, while a food web is a more complex network of interconnected food chains.

Front

What is precipitation?

Back

Precipitation is any form of water, liquid or solid, that falls from the atmosphere to the Earth's surface, including rain, snow, sleet, and hail.

Front

What is carrying capacity?

Back

Carrying capacity is the maximum number of individuals of a species that an environment can sustainably support.

Front

What is energy transfer in an ecosystem?

Back

Energy transfer in an ecosystem refers to the movement of energy through the food chain, where energy decreases at each trophic level.

Front

What role do producers play in an ecosystem?

Back

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