Every time you eat a cookie or candy bar, your blood sugar increases. This triggers an increase in the hormone insulin. Insulin<span> is a hormone made by the pancreas which allows your body to use sugar (glucose) from carbohydrates in the food that you eat, or to store glucose for future use. </span>Insulin<span> helps keeps your blood sugar level from getting too high (hyperglycemia) or too low (hypoglycemia).</span>
Answer:
As with sea horses, sea dragon males are responsible for childbearing. But instead of a pouch, like sea horses have, male sea dragons have a spongy brood patch on the underside of the tail where females deposit their bright-pink eggs during mating.
Answer: The producers refers to green plants that carry out the process of photosynthesis in order to produce food for themselves and others. The principal function of producers is to manufacture food for themselves and all other living organisms.
The consumers refers to those living organisms that can not produce their own food and have to depend on the food produce by others. Consumers can be categorized into primary, secondary and tertiary consumers depending on where they are located on the trophic levels. They can also be classified as herbivores, carnivores and omnivores depending on the type of food they eat. The major function of consumers is transference of energy. Consumers transfer the energy they obtain from the food they eat to those animals that feed on them.
The decomposers are those micro organisms that are majorly found in soils.The principal function of decomposers is to break down dead organic matters so that they can be absorbed by the roots of plants. The broken down organic substances serve as nutrients, which the plants used to grow and develop.
These three types of organisms work together in the ecosystem to maintain the balance of the ecosystem.
Answer:
This event is telling the evolution by natural selection. This is the directional selection where most adapted animals will survive. According to Darwin, the new species arise from a single ancestor due to variation.
It had also seen in the Finches. All the new species of Finches came from a pre-existing seed-eating Finch. When the environment was favorable the Finches were herbivore and feed on seeds.
When the number of birds increases, there is a competition between them. Because the food source was limited. To prevent this competition
some of them go for different foods like insects, fruits, etc.
This food habit change also changes their morphology and separate them from their ancestor.
Similar manner, when draught condition occurs, some of the seed-eating birds become carnivore to survive this new climate. As the environmental condition continues for a long time, the number of carnivore animals will increase in number.
Because due to drought conditions, the availability of seed will decrease. Thus the carnivore birds will be more in number and the herbivore birds will gradually eliminate, as they can't cope with the new climate.
