Matter in Ecosystem

Producers obtain their energy by

• the process of hunting for prey

• the process of eating plants

• the process of photosynthesis to make their own food from sunlight

• the process of breaking down once living things

All living parts of an ecosystem (plants, animals, and decomposers) are depend on one another for

• food

• energy

• cycling matter

• food, energy, and the cycling of matter

The food web shows

• many possible interactions and feeding relationships beween the organsims in the ecosystem

• a nice picture of what lives in the ecosystem

• the symbiotic relationships

• the keystone species

Decomposers are important to ecosystems because they

• return vital nutrients to the ecosystem

• capture energy from the Sun

• are producers

• can be omnivores

The cycling of matter is important because

• Matter can be created and destroyed

• Only a limited amount of matter is available so it has to be recycled

• Matter can only be found in a solution

• Bacteria use matter to convert organisms into solar energy
