Question

standards check ls 4b populations of organisms can be categorized by the functions they serve in an ecosystem. plants and some microorganisms are producers - they make their own food. all animals, including humans, are consumers, which obtain their food by eating other organisms. decomposers, primarily bacteria and fungi, are consumers that use waste materials and dead organisms for food. food webs identify the relationship among producers, consumers, and decomposers in an ecosystem. word help: categorized to put into groups or classes 8. list name three roles bacteria can play in an ecosystem. endospores most bacteria do well in warm, moist places. some species of bacteria die in dry and cold surroundings however, some bacteria form endospores to survive these kinds of conditions. an endospore is a thick, protective covering that forms around the dna of a bacterium. the endospore protects the dna from changes in the environment. when conditions are good the endospores break open, and the bacteria begin to grow. classification scientists can classify bacteria by the way the bacteria get food. there are three ways for bacteria to get food: consume it, decompose it, or produce it. • consumers eat other organisms. • decomposers eat dead organisms or waste • producers make their own food. some bacteria can make food using the energy from sunlight. decomposers, such as the ones helping to decay this leaf, return nutrients to the soil this allows other living things to use those nutrients cyanobacteria cyanobacteria are producers. these bacteria have a green pigment called chlorophyll chlorophyll traps energy from the sun. the cell uses the energy to make food some scientists think that chloroplasts of plants and algae are similar to cyanobacteria. they think that long ago, cyanobacteria entered plant cells to obtain energy. according to this idea, the bacteria made food for the plant cells. in return, the plant cells protected the bacteria. this relationship may have led to the evolution of plants.

Explanation:

The text mentions that bacteria can be consumers (eat other organisms), decomposers (eat dead organisms or waste), and producers (make their own food).

Answer:

1. Consumers
2. Decomposers
3. Producers
