Review - How Organisms Obtain Energy

Front

What is the primary source of energy for most organisms?

Back

The primary source of energy for most organisms is the sun, which provides energy for photosynthesis in plants.

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.

Front

What is cellular respiration?

Back

Cellular respiration is the process by which cells convert glucose and oxygen into energy, carbon dioxide, and water.

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 in an ecosystem, illustrating how different organisms are related through feeding relationships.

Front

What role do producers play in an ecosystem?

Back

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

Front

What are consumers?

Back

Consumers are organisms that cannot produce their own food and rely on consuming other organisms for energy.

Front

What is nitrogen fixation?

Back

Nitrogen fixation is the process by which nitrogen gas from the atmosphere is converted into ammonia or related compounds in soil, making it usable for plants.

Front

What is the role of decomposers in an ecosystem?

Back

Decomposers break down dead organic matter, recycling nutrients back into the soil and making them available for producers.

Front

What is the difference between herbivores and carnivores?

Back

Herbivores are organisms that primarily eat plants, while carnivores are organisms that primarily eat other animals.
