Please answer the following questions:
1. Biodiversity Aa Aa Ecologists are interested in quantifying different kinds of biodiversity. In each of the two studies outlined here, which kind of biodiversity are ecologists studying? Ecologists draw blood samples from basking shark (Cetorhinus maximus) specimens caught froma single large population in the Atlantic Ocean Ecologists establish 20 small areas, called plots randomly scattered across a California grassland hey count the number of different pl present in each plot. ant species From each blood sample, the ecologists isolate DNA. By noting how many species appear in the plots, the ecologists are able to estimate the number of species in the entire grassland Comparing several DNA sequences across the individuals that were sampled, the ecologists are able to estimate the variation in DNA sequences in the entire population O Ecosystem diversity O Species diversity O Functional diversity Genetic diversity O Functional diversity O Ecosystem diversity O Species diversity Genetic diversity One way to think about the importance of biodiversity is simply to think in terms of natural capital: the roles that genes, species, ecosystems, and ecological processes play in supporting human society and a healthy biosphere Which of the following are benefits provided by biodiversity? Check all that apply Maintaining clean water Decomposing dead organisms Stopping human overpopulation Providing nutritious foodsExplanation / Answer
In first case, the ecologists are trying to compare DNA sequences from blood samples of basing sharks.
This is measuring genetic diversity.
Option d is the answer
In second case, the ecologists tried to make small patches of land and measured different types of plant species in each patch of land.
This is species diversity.
Option d is the answer.
