Predators are the keystone species because they limit the population of prey.
<h3><u>Explanation:</u></h3>
Predators are those species which hunt for other animals to consume them as food and live. Where prey are those animals who are being hunted and killed by predators.
Keystone species are those species whose absence or removal from a ecosystem will greatly reduce the diversity from the ecosystem to a huge extent.
Now, if a predator like lion is eliminated from the ecosystem, then the prey like deer, goats etc in the ecosystem will live and reproduce at a very high rate, which will greatly increase the population density of these species. So the food for them will be killed at a very high rate, decreasing the plant varieties and population. So the overall diversity in the ecosystem will be highly reduced.
So the predators like lions, tigers, etc are the keystone species of an ecosystem.
A food pyramid is a represntation of predatory relationships in the food chain.
The _____ passively diffuses oxygen and carbon dioxide in and out of the cell.Through the plasma membrane, oxygen and carbon dioxide diffuses passively.
However, it is thru a transport that they in act to diffuse, -concentration gradient.
Answer: carbohydrates is composed of amino acids
Explanation: carbohydrate functions as an energy giving food in the body. Examples are rice, casssava and maize. The molecular structure of carbohydrate is (CH20)n. Carbohydrate has three subtypes:
(1) Monosaccharides: They are simple sugar and consists of a number of carbons(C) which ranges from 3 to 7.
(2) Disaccharides: They are formed when two Monosaccharides undergo a dehydration reaction which is also known as condensation reaction. thanks
(3) Polysaccharides: They consist of a long chain of branched or unbranched
Monosaccharides Monosaccharides linked by covalent bonds.
Carbohydrates is not composed of amino acids but rather protein is composed of amino acids.
