This is false. Organisms may play several important roles in an ecosystem. Consider for example and ocean shore environment occupied by a particular species of crab. The crabs are scavengers and eat any organic matter they encounter. They therefore play an important role in the cycling of nutrients in the ecosystem. The crabs are however also an important source of food for a range of other species occupying the same habitat, including octopi, certain fishes and sea otters. Therefore, the crabs are an important part of the food web in the ecosystem. Many species similarly occupy multiple important roles in an ecosystem.
<span>In anatomical terms, this plane would be known as the midsaggital plane. This plane bisects the body of the organism along its midline, yielding two symmetrical halves. Since such a plan would run right along the ribcage of the turkey, dividing it as such, it would be the accurate anatomical descriptor for such a division.</span>
Answer: Directional selection
Explanation:
In the population genetics, directional selection is the mode of selection during which the extreme phenotype are favored more than the other phenotype.
This causes the allele frequency to shift towards the time in the direction of that particular phenotype.
Here, in the question the acid tolerant plant species is favored over the other phenotype.
Hence, the correct answer is option D
Jupiter, because its the biggest.
Food-borne illness: contamination that results from the spread of bacteria from meat to vegetable, various microorganisms get in the food which is rich in nutrients therefore letting the bacteria grow.
