Answer: Carbon 12 and Carbon 13
In plant, the ratio of carbon 12 and carbon 13 isotopes is different depending upon the plant photosynthesis. The distribution of these isotopes in plant tissue can indicate the path way of carbon metabolism that is either C3 fixation or C4 fixation. This help scientist to know if the plant consumed by organism is C3 plant or C4 plant by measuring the isotopic signature of their collagen and other tissues.
This can help scientist know which plant is consumed by animals.
Answer:
Here, is the question with the explanations to pick from to complete the question
Tropical rainforests have high species richness of trees. Which of the following statements provides the MOST reasonable explanation why animal species richness is also high in tropical rainforests?
Animals are unable to adapt to climate variability in higher latitudes.
Animals have had the same amount of time to evolve in rainforest areas as trees.
Animal diversification rates are higher than those of trees.
Animals have diversified into the vast number of niches provided by tree diversity
The last option is the most reasonable one
Our answer is:
Animals have diversified into the vast number of niches provided by tree
Explanation:
The reason is that a lot of species are highly specialized to occupy a particular niche. Where that favourable niche exists, the population of that species increases as its offspring colonize new areas.
Then the submerged aquatic plants will note be able to receive light for photosynthesis. then those submerged aquatic plants will not have food/nutrients to survive, hence die. aquatic animals will not receive sufficient oxygen from those submerged aquatic plants, hence die also.
decomposes will breakdown all dead organisms to release carbon dioxide, and also deplete oxygen concentration during decomposition process.
eventually, habitat is rendered not livable. only the algae continue to proliferate uncontrollably at the water body surface.
