Answer:
C. The population of a community stabilizes and doesn't change in size or scope
Explanation:
The climax communities are the communities that have reached the optimal number of species, as well as the optimal number of individuals of the species in the environment in accordance to the available food sources and space. These communities are in a state of equilibrium. Basically, the ecosystem has just the right amount of species, and just the right number of individuals of the species that it can support. All these species interact with each other, benefit from each other, and contribute to the well being of the ecosystem, living in perfect balance. The climax communities also need time to be established, but they also are communities that have not experienced disturbances for quite some time.
I'm not sure how many reasons you want, but here are 3 reasons.
1. Frogs can breathe on land and in water, whereas tadpoles can only breathe in water.
2. Frogs can go on land, and tadpoles cannot.
<span>3. Tadpoles do not have limbs, frogs do.</span>
Scientists compare DNA from living organisms to identify similarities between species
Answer: Option D
<u>Explanation:</u>
The DNA content of any organism codes for its behavior and other activities, the nucleic acid is the only encryption that takes the internal code of the parents to the off springs, hence a comparison in the evolution can be done only through testing the DNA content.
The information in the DNA also tells us the evolution of species along with their relationship with each other. Thus helps in the construction of the phylogenetic tree.
