<span>The correct answer should be d. The rainforest is important to life as a whole on the planet. Without them the global warming phenomenon would skyrocket because of massive spikes of carbon dioxide that is man made. Without them the animal biomes would also get destroyed because suddenly thousands and thousands of species would be left without a home so you would disrupt nature. Without them the Earth would be ravaged by bad things.</span>
Answer:
In nature, populations are usually evolving. The grass in an open meadow, the wolves in a forest, and even the bacteria in a person's body are all natural populations. And all of these populations are likely to be evolving for at least some of their genes. Evolution is happening right here, right now!
To be clear, that doesn't mean these populations are marching towards some final state of perfection. All evolution means is that a population is changing in its genetic makeup over generations. And the changes may be subtle—for instance, in a wolf population, there might be a shift in the frequency of a gene variant for black rather than gray fur. Sometimes, this type of change is due to natural selection. Other times, it comes from migration of new organisms into the population, or from random events—the evolutionary "luck of the draw."
I hope this helps a little bit.
Hi!
Organisms might compete for food, pH, territory, and water.
