Answer:
Metabolism consists of all the energy transformation reactions in an organism. (Ans. B)
Explanation:
Metabolism is defined as the total sum of the chemical reactions which synthesized in every cell of living things and provides energy for formation of new organic materials and vital processes (such as movement, growth, reproduction and development).
In living metabolism, enzyme mediated chemical reactions takes place. Energy which comes from nutrients and solar energy fueling multistep reactions and converting into the molecules which is necessary for maintenance and growth.
Answer:
C
Explanation:
Behavioural reproductive Isolation. This is the type of behaviour isolation that do not allow some members of a population to mate with the others. It might be due to how they find and choose mates. Some species have very unique rituals and behavior that has to take place before reproduction can occur so most of the time it is a form of pretty-zygotic barrier that happens before reproduction can happen.
Answer:
It will remain a part of the environment
Explanation:
Energy cannot be destroyed but can change from one sate to another. Usually in a food chain animals eaten and the energy is passed from one animal to the next. In the case of larger animals the energy is only made available is they pass away or lose an appendage such as a tooth or antlers, that other animals can feed on.
If a shark is not preyed on and remains in the ecosystem, it's energy will not be cycled but this animal will get larger and larger.
Should a shark pass away and nothing feeds on it there are two things that will happen:
- Energy will be stored and the animal will eventually become volatile or slowly disintegrate and the energy will be released from the atoms and molecules when the bonds are eventually broken by chemical reactions brought on by the environment (sun. wind, currents, etc).
- The animal will eventually solidify and may turn into stone. The energy will be locked into the animal and will be encased and become a part of the substrate
It is not likely that a shark will keep it's energy and not be eaten by other animals after death but on the chance that it does it may slowly disintegrate or become solidified.
A tree's mass is mainly biomass. During photosynthesis plants, the carbon is used to transform the Sun's energy into chemical energy that is captured in the bonds of carbon molecules made of atmospheric carbon dioxide and water
Extremophiles such as halophiles and extreme thermophiles are archeas which live in and can survive in extreme conditions.
Halophiles thrive in high salt concentrations, while extreme thermophiles are used to temperatures like in hot springs (so, very high).
