Answer:
Without Photosynthesis plants and animals won't exist.
Explanation:
Photosynthesis is a process through with plants and other living things makes food. It is a chemical reaction which is endothermic in nature that uses sunlight to turn Carbon dioxide into sugar,in order for the cells to use to perform Work.
The occurance of volcano as described in the question happens to disrupt the Continuous occurance of photosynthesis and this in turn will greatly affect the existence of plants and animals. We can simply say plants and animals can not exist without Photosynthesis.
This is because photosynthesis releases a large amount of oxygen into the atmosphere , of which both plants and animals make use of.
If I may ask how do you feel staying in an atmosphere with limited supply of oxygen ? Of course you feel suffocated and you feel you are dieing. That is exactly the scenario we are analysising now.
Some group of sea organism that doesn't depends on photosynthesis will still survive never the less. But organisms that takes in Oxygen and gives out Carbondioxide have a higher rate of not surviving.
In every ecosystem, there are different organisms that interact with each other in a particular environment.
The components of an ecosystem interact and interrelate with the ones that form part of another. Every ecosystem is related to another one.
For example, in a food chain, a bird eats a fish, both animals belong to different ecosystems, but they are connected with each other.
Answer:
<em>The correct option is C. plant species it eats</em>
Explanation:
A habitat can be described as a location or a place where an organism lives.
A niche can be described as the role that it plays in a habitat or an ecosystem.
Option C mentions the plant species that a grasshopper eats. Hence, it will be the niche for the grasshoppers not its habitat.
Other options like option A, continents where the grasshoppers live and option B, locations where it shelters can be described as the habitat.
Answer:
Change occurs in the heredity characteristic of living organism over time.
Explanation:
Change occurs in the heritable characteristics of living organisms with the passage of time is known as evolution. Evolution consist of three basic principles which are variation, heredity, and differential fitness. The organisms evolved with the passage of time due to change in the environmental conditions which able them to survive in that harsh climatic conditions and those which is not evolved can't survive and in the end extinction occur.
Answer:
The possible genotype of this cross is RW
Explanation:
This question involves a single gene coding for radish color. The allele for red radish (R) is incompletely dominant over the allele for white radish (W), hence, a third intermediate phenotype is formed when they combine (RW).
In this cross, a pure-breeding red radish (RR) is crossed with a pure breeding white radish (WW) to create the F1 offspring. The red radish will produce gametes R while the white radish will produce gametes W, hence, using a punnet square (see attached image), the F1 offspring will have the genotype: RW.
