A hetereotroph

• is a consumer

• is a producer

• is an autotroph

Organisms that make their energy /organic compounds from inorganic/abiotic sources

• consumer

• decomposer

• saprotrophs

• autotrophs

Organisms that make their energy /organic compounds from organic/biotic sources

• populations

• heterotrophs

• producers

• autotrophs

Species are

• organisms that can interbreed but produce infertile offspring

• organisms that reproduce asexually

• organisms that cannot reproduce

• organisms that can interbreed to produce offspring

What is the role of producers in the environment?

• recycle nutrients

• produce oxygen

• produce the initial energy by trapping it in glucose

• balance populations in the ecosystem

What is the role of consumers in the environment?

• recycle nutrients

• produce oxygen

• produce the initial energy by trapping it in glucose

• balance populations in the ecosystem

What is the role of detritivore in the environment?

• break down dead plants and animals and recycle nutrients

• produce oxygen

• produce the initial energy by trapping it in glucose

• balance populations in the ecosystem
