They use the process known as decomposition- much like the name!
Answer:
directional selection
Explanation:
Directional selection is the most common type of natural selection and occurs when some individuals with characteristics favorable to the conditions of the environment in which they live, have survival advantages over individuals who do not have this advantage, who end up dying.
Imagine, for example, a graph showing the directional selection in the same species of moths. Moths of the same species have white and brown collations, in summer, brown moths can camouflage themselves on tree trunks, while white moths cannot and are easily captured by their predators, which means that the amount of white moths decrease. In this graph, the population of white moths would be at a minimum, at the same time that the population of brown moths would be at maximum.
However, with the arrival of the reverse, snow begins to cover the trees, allowing white moths to camouflage themselves more easily. The brown moths, then, are very exposed to predators, causing their population to reach the minimum while the population of white moths reaches the maximum.
The population size of a predator species is directly controlled by the population size of it's prey. If the predator has no prey the population size will go down because they have no food.
Answer:The lengthy small intestine receives secretions from the ______pancrease______ and ______liver______, completes digestion of the nutrients in _________chyme_______, absorbs the products of digestion, and transports the remaining residues to the ________large________ intestine.
Explanation: digestion of food is necessary for absorption of nutrients. In this process food is broken down into forms that can be absorbed by the body . food is broken down by the teeth and the enzymes in saliva,when it is in the mouth. From there it moves to the stomach through the oesophagus. In the stomach, the content is further mixed with enzymes and the churning breaks down food further.From the stomach food moves to the small intestine. In the small intestine, digestive enzymes from the pancreas and liver acts on food. The small intestine is where digested food is absorbed.it has a large surface area and finger-like projection called villi to carry out the function of absorbing nutrients.
From there, undigested food us passed to the large intestine from where it is passed out through the anus
