I am it sure but that is what you generally call it or just compliments
Darwin concluded that the finches all shared a common ancestor but had developed different beak structures. The second sentence best describes as an ecosystem.
Explanation:
- When Charles Darwin traveled to the Galapagos Islands, he observed 14 distinct varieties of finches on the islands Darwin also observed that each finch variety ate a different type of food and lived in a slightly different habitat from the other finches, Darwin concluded that the finches all shared a common ancestor but had developed different beak structures. The second sentence best describes as an ecosystem.
- An ecosystem is a huge group of living organism such as plants,animals, micro-organisms in a particular area.
- An ecosystem is a community of living organisms related with the nonliving components in the environment, together interacting as a system.
- its abiotic constituents, includes minerals, climate, soil, water, sunlight, and all other nonliving elements, and its biotic constituents, consists of all its living members.
I think C would be correct
One will be due to climatic change or it might be coz of evolution
Answer:
Option C - The sympatric salamander populations evolved their present body sizes after they became sympatric.
Explanation:
First, note the definitions of each terms.
1) Sympatric occurs when organisms especially of same species occurring in the same, or in overlapping territory, do not interbreed.
2) Allopatric occurs when organisms are NOT living in the same territory and thus unable to crossbreed.
On 1st QUESTION
The argument would be strengthened by the failure of P. cinereus and P. hoffmani to crossbreed making traits for body size to become distinct (dissimilar) in each specie.
On 2nd QUESTION
Definitely, salamanders species occurring in the territory, do not interbreed after they became sympatric, thus, making characters among same species to be increasingly different over generations.
