Answer:
A community
Explanation:
In ecology, a community is used to describe a group of organisms of different species populations that live and interact together at a particular time in a common habitat or ecosystem.
The two cardinals, colony of ants, a wasp’s nest, two squirrels, and the millions of bacteria represent a community of different organisms dwelling at the backyard tree.
Answer:
A source from which organisms generally take elements is called exchange pool (option B).
Explanation:
Options for this question are:
- <em>Food web.</em>
- <em>Exchange pool.</em>
- <em>Reservoir.</em>
- <em>Biotic community.</em>
The term exchange pool is related to the biogeochemical cycles that exist in nature, referring to the source from which elements present in the environment become part of living organisms.
<u>Exchange pools are the biotic components</u> -like animals and plants- of an ecosystem, which determine the passage of elements between living beings. An element can remain as a reservoir (abiotic) in the soil, and then be incorporated into the exchange pool.
An independent variable is a variable which change is not affected by that of another variable. By process of elimination you can take out B and C. An independent variable can also change so that takes out A. That leaves D.
Answer:
a gradual increase in the overall temperature of the earth's atmosphere because of the greenhouse effect caused by increased levels of pollutants.
Explanation:
Activated charcoal adsorbs many noxious substances—medical drugs, phytotoxins and poisonous chemicals—onto its surface, preventing their absorption from the gastrointestinal tract.
<h3>What is activated charcoal ?</h3>
Activated carbon, sometimes known as activated charcoal, is a type of carbon that is frequently used for a variety of purposes, including the filtration of impurities from water and air. It is treated to have tiny, low-volume holes, which expand the surface area open to chemical reactions or adsorption.
- For some poisonings, activated charcoal is utilised as an emergency therapy. It aids in preventing the body from absorbing the toxin from the stomach. To treat severe poisoning, activated charcoal may occasionally be given in multiple doses.
