Popalo-Intro To Ecology

the process by which carbon dioxide and water are converted to carbohydrates; uses energy from the oxidation of inorganic compounds.

the different feeding positions in a food chain or web.

organisms that produce organic compounds from energy and simple inorganic molecules; also known as producers.

organisms that eat a diet consisting mainly of herbivores or other carnivores.

organisms that use the energy stored in chemical compounds to make organic molecules by chemosynthesis.

organisms that depend on producers or other types of organisms for food.

organisms that consume the remains of dead plants (detritus).

organisms that consume dead organisms and other organic waste.

organisms that consume only producers such as plants or algae; form a necessary link between producers and other consumers.

organisms that depend on producers or other types of organisms for food; also called consumers.

organisms that depend on producers or other types of organisms for food; also called consumers.

organisms that eat both plants and animals as primary food sources.

organisms that use energy from sunlight to make food by photosynthesis; includes plants, algae and certain bacteria.

organisms that produce organic compounds from energy and simple inorganic molecules (organism can be primary produces, secondary producers etc.).

carnivores that mainly eat the carcasses of dead animals.

a step in the food chain of an ecosystem. organisms are classifying into trophic levels depending on their feeding behavior.

when a change at the top of the food chain works it’s way down to the lower trophic levels and eventually changes the balance in the relationships between numerous species.

a species that plays an especially important role in its community; major changes in the numbers of a keystone species affect the populations of many other species in the community.
