“An ecosystem is a community of living organisms in conjunction with the nonliving components of their environment (things like air, water, and mineral soil), interacting as a system. These biotic and abiotic components are regarded as linked together through nutrient cycles and energy flows. As ...
The basic biotic components of an ecosystem include (a) producers鈥攖he photosynthetic organisms that convert solar energy into chemical energy, (b) consumers that serve as ecosystem regulators, and (c) decomposers that recycle finite material resources. These components, in turn, are composed of ...
How do decomposers interact with their ecosystem? Why are plants important for essential ecosystem services? How do supply ecosystem services reduce flooding? How effective is the ecosystem of earth? How does an ecosystem change during succession?
The label of detritivores and decomposers is often used interchangeably, but experts do not consider all decomposers to be detritivores. Detritivores are a special type of decomposer that ingests large lumps of matter. In contrast, decomposers generally refer to microorganisms likebacteria, protists,...
Fire ecology is the scientific discipline that looks at natural processes involving fire in an ecosystem. It also comprises the ecological effects, the interactions between fire and the abiotic and biotic components of an ecosystem, and the role of fire as an ecosystem process. Many ...
among species in communities interact. For example, high predation rates can reduce competition among prey species. Because of this complexity, ecologists are keenly interested in understanding the complex web of interactions among the various plants, herbivores, carnivores, and decomposers in a ...
Bt maize harboured fewer parasitoids (Braconidae, Tachinidae) of the European corn borer, the main target pest of Lepidoptera-active Bt maize, compared with non-Bt maize. Similarly, sap beetles (Nitidulidae), that are associated with Lepidoptera damage, were recorded less in Bt maize. In some ...
Each of the following questions/statements have four suggested answers. Rewrite the correct answer in each case: This is not a trophic level in an ecosystem. View Solution Why is the length of food chain in an ecosystem generally limited to 3-4 trophic levels. ...
These are some of the internal parts that can be found in an earthworm: The mouth cavity is the opening for the digestive tract that helps obtain nutrients from the soil. The pharynx is the muscular throat that pushes food down into the esophagus. The esophagus is the tube that connects ...
What is the difference between ecosystem services and ecosystem functions? What happens during primary ecological succession? How do decomposers help plants? What is tolerance in terms of ecological succession? How is Surtsey an example of ecological succession?
