Since the pyramid narrows from bottom to top, we can conclude that the amount of energy keeps on decreasing as we move to a higher trophic level.
Explanation:
Ecological pyramid are graphical representation of data that shows the number of organisms,amount of energy and amount of biomass at each trophic level in a food chain.
Food chain is a sequence of organism who are related to each other by the process of Eating and being Eaten up.
The base of the ecological pyramid represents the producer or the first trophic level while the apex of the pyramid represents the cosumers at higher levels of food chain; other consumer trophic levels are in middle.
There are three types of Ecological pyramids:
- Pyramid of number: This shows the number of organisms of a population present at each trophic level.
- Pyramid of energy: This shows the amount of energy available at each trophic level and clearly depicts the energy loss at successive trophic level.
- Pyramid of biomass: This pyramid represents the total dry weight of living beings present at each trophic level.
The pyramid of Energy is always an upright pyramid because amount of energy transferred from one trophic to next keeps on decreasing as the energy is lost in form of heat and is also used up by the organism at a given trophic level and only the remaining is part to the next.
Minerals are classified into groups primarily on the basis on their chemistry, specifically base on the anions within the chemical formula. Minerals are naturally occurring materials that are inorganic in nature and solid in form. It cannot exist as a liquid or a gas. It is made from the physical and chemical processes or the geological processes happening on Earth and not from biological processes of living organisms. It may consists of a single chemical or more in a form of compound. They are classified base on the anion present like carbonates, sulfides, silicates, oxides, hydroxides, halides, borates, phosphates and sulfosalts.
Answer:
sweat cools the surface of the skin and reduces body temperature
Explanation:
Protection: eccrine sweat gland secretion aids in preserving the skin's acid mantle, which helps protect the skin from colonization from bacteria and other pathogenic organisms.
Answer:
For photosynthesis
Explanation:
Photosynthesis is needed to make glucose for the plants.
