What is the term for the process of using living organisms to detoxify polluted ecosystems?

Bioremediation is a process that uses mainly microorganisms, plants, or microbial or plant enzymes to detoxify contaminants in the soil and other environments.

What is it called when we use living organisms to detoxify a polluted ecosystem?

Bioremediation is a branch of biotechnology that employs the use of living organisms, like microbes and bacteria, in the removal of contaminants, pollutants, and toxins from soil, water, and other environments. Bioremediation is used to clean up oil spills or contaminated groundwater.

When the number of organisms within a species drops to a level so low that extinction is possible what is the species called?

An endangered species is a type of organism that is threatened by extinction. Species become endangered for two main reasons: loss of habitat and loss of genetic variation.

Why do toxins accumulate at such high levels in carnivores quizlet?

Why do toxins accumulate at such high levels in carnivores? The biomass at any given trophic level is accumulated from a much larger toxin-containing biomass ingested from the level below. Because they are at the top of the energy pyramid, they eat the most food and so accumulate the most toxins.

What does bioremediation refer to quizlet?

Bioremediation is the process of cleaning up environmental sites contaminated with chemical pollutants by using living organisms to degrade hazardous materials into less toxic ones.

What do ecologists call a community?

In ecology, a community is a group or association of populations of two or more different species occupying the same geographical area at the same time, also known as a biocoenosis, biotic community, biological community, ecological community, or life assemblage. The term community has a variety of uses.

Which term is a method to restore biodiversity to a polluted or damaged area?

Ecological restoration is the process of assisting the recovery of an ecosystem that has been degraded, damaged, or destroyed.

What is meant by the term ecosystem engineer?

Ecosystem engineers are species that modify their environment in a significant manner, creating new habitats or modifying existing ones to suit their needs. Through their activities ecosystem engineers significantly affect other species by providing and maintaining microhabitats that would not otherwise exist.

What is meant by the term ecological succession?

Ecological succession is the process that describes how the structure of a biological community (that is, an interacting group of various species in a desert, forest, grassland, marine environment, and so on) changes over time. … The structure of this community becomes more complex as new species arrive on the scene.

What is the term for a group of organisms of the same species living in a particular area?

Population: A group of organisms of the same species, living in the same area at the same time.

What is the term for the complete disappearance of a species?

Extinction is the complete disappearance of a species. Extirpation, also called local extinction, is the disappearance of a species only from a given area. … When many species become extinct in a short time, the event is termed a mass extinction.

What term is used when the population of a species begins declining rapidly?

endangered species, any species that is at risk of extinction because of a sudden rapid decrease in its population or a loss of its critical habitat. Previously, any species of plant or animal that was threatened with extinction could be called an endangered species.

Why do toxins accumulate?

Bioaccumulation is the gradual accumulation of substances, such as pesticides or other chemicals, in an organism. Bioaccumulation occurs when an organism absorbs a substance at a rate faster than that at which the substance is lost or eliminated by catabolism and excretion.

What is predation in an ecosystem?

In predation, one organism kills and consumes another. Predation provides energy to prolong the life and promote the reproduction of the organism that does the killing, the predator, to the detriment of the organism being consumed, the prey. Predation influences organisms at two ecological levels.
