These small herbivores eat dozens of kilograms (pounds) of giant kelp every day. Energy flow & primary productivity. Next lesson. © 1996 - 2020 National Geographic Society. As the bodies of large animals such as whales sink to the seafloor, detritivores such as worms break down the material. Biotic and abiotic factors work together to create a unique ecosystem. Biomass decreases with each trophic level. Roughly speaking, these levels are divided into producers (first trophic level), consumers, and decomposers (last trophic level).

Algae, whose larger forms are known as seaweed, are autotrophic. Children will know: how plants make food; how animals find food in different seasons; dangers to meadow food chains; and, other topics. As a result, prey animals like howler monkeys, leaf-cutter ants, and iguanas flourished. The ants became so numerous that they destroyed the rainforest, killing all the trees and other plants. A food web is all of the food chains in an ecosystem. the sudden shaking of Earth's crust caused by the release of energy along fault lines or from volcanic activity. If the sea otter population shrinks due to disease or hunting, urchins devastate the kelp forest. DDT accumulates in soil and water. More information: process by which some microbes turn carbon dioxide and water into carbohydrates using energy obtained from inorganic chemical reactions. species at the top of the food chain, with no predators of its own. process by which plants turn water, sunlight, and carbon dioxide into water, oxygen, and simple sugars. developed, densely populated area where most inhabitants have nonagricultural jobs. Salmon runs can be diverted by landslides and earthquakes, as well as the construction of dams and levees. A meadow is an open habitat, or field, vegetated by grass, herbs and other non-woody plants.Meadows may be sparsely covered with trees or shrubs, as long as they maintain an open character. waste material produced by the living body of an organism.

Detritivores are organisms that eat nonliving plant and animal remains. Finally, bacteria in the soil decompose the remains.Algae and plankton are the main producers in marine ecosystems. The mule deer can then be eaten by a lion or bobcat. At the top of the system are the apex predators: animals who have no predators other than humans. Gerald is studying the plants and animals of a meadow. - Ann. Illustration Gallery. Xinwei Wu.

In kelp forests, seaweeds known as giant kelp provide shelter and food for an entire ecosystem. highly infectious and sometimes deadly disease with symptoms of itching sores and severe headache, caused by lice. A salmon run is a river where salmon swim. BiomassFood webs are defined by their biomass. DDT was a major reason for the decline of the bald eagle, an apex predator that feeds primarily on fish and small rodents.
