Energy flow in marine ecosystems

Front

What is chemosynthesis?

Back

Chemosynthesis is the process by which certain organisms, such as those found in hydrothermal vents, convert inorganic compounds into organic matter using chemical energy, rather than sunlight.

What is a producer in an ecosystem?

Back

A producer is an organism that uses sunlight to make its own food through the process of photosynthesis.

Front

What is the role of herbivores in an ecosystem?

Back

Herbivores are organisms that get energy by eating only plants, playing a crucial role in transferring energy from producers to higher trophic levels.

Front

What is a predator?

Back

A predator is an organism that hunts and eats other organisms (prey) for energy.

Front

How do predator and prey populations interact?

Back

Predator populations typically lag behind prey populations because an increase in predators leads to a decrease in prey, which in turn can lead to a decrease in predator numbers.

Front

What is the difference between a herbivore and a carnivore?

Back

A herbivore is an organism that eats only plants, while a carnivore is an organism that eats only other animals.

Front

What is the significance of producers in marine ecosystems?

Back

Producers are vital in marine ecosystems as they form the base of the food web, converting sunlight into energy that supports all other life forms.

Front

What is the energy flow in a marine ecosystem?

Back

Energy flows from producers (like phytoplankton) to primary consumers (herbivores), then to secondary consumers (carnivores), and so on, forming a food chain.

Front

What is a food web?

Back

A food web is a complex network of feeding relationships among various organisms in an ecosystem, illustrating how energy and nutrients flow.

Front

What is the role of decomposers in an ecosystem?

Back

Decomposers break down dead organic matter, recycling nutrients back into the ecosystem and supporting the growth of producers.
