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.
If nearly 79% of atmosphere is nitrogen, how could there be a shortage of nitrogen in some soils? Nitrogen must be converted into nitrates before organisms can use it. If soil lacks nitrogen fixing bacteria, then it has few nitrates for the plants to take in.
Answer:
yes,because rabbit is one of the food sources of fox .If rabbit population decrease, fox population will also decease due to lack of food.

Answer:
d. Calvin cycle
Explanation:
During the light reactions or photochemical reactions of photosynthesis, chlorophyll molecules absorb sunlight and convert light energy into assimilatory power in the form of the electron carrier molecule nicotinamide adenine dinucleotide phosphate (NADPH) and the ATP.
The ATP and NADPH used as a source of energy to fix or reduce carbon dioxide into glucose.
The reduction of carbon dioxide to glucose occurs in the stroma of the chloroplast. The reactions of the conversions are called the Calvin cycle.
