What is an autotroph?

Back

An autotroph is an organism that makes its own energy from sunlight, such as plants and some algae.

Front

What is a food web?

Back

A food web is a group of interconnected and independent food chains that shows energy flow in an ecosystem.

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 complex network of interconnected food chains.

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.

Front

What is the significance of marine biodiversity?

Back

Marine biodiversity is crucial for ecosystem resilience, providing resources for food, medicine, and maintaining ecological balance.

Front

What is the primary source of energy for marine ecosystems?

Back

The primary source of energy for marine ecosystems is sunlight, which is harnessed by autotrophs.

Front

What is the role of decomposers in marine ecosystems?

Back

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