Question

Scientists around the world are collaborating to understand how deforestation, climate change, and natural processes will interact to affect one of the most productive and biodiverse ecosystems on Earth.

This box-and-arrow model summarizes some of the feedback links observed in the Amazon rain forest. Select True or False for the statements that follow, based on whether they are represented by the model. (Note that the boxes and arrows in this model are used differently than those in the nutrient cycle models).

T/F The burning of fossil fuels increases atmospheric CO₂.

T/F Tree growth reduces atmospheric CO₂.

T/F The death of trees promotes the invasion of grasses.

T/F An increase in CO₂ increases the frequency of droughts.

T/F Drought increases the frequency of forest fires.

Accepted Answer

Hello everyone and welcome to today's video. So the typical environment of a particular organism, population or community is called. Which of these following terms? Let's begin. Go over each of them. So we may be in solving the problem. Let's begin by answer choice. A bio bio are the sets of idiotic factors such as temperature, humidity, sunlight and more that may govern a certain area. So for example, tropical rainforests are buying homes because of these. These are not going to be the typical environment that the organism is going to be living in. And we're going to cancel this out. Then we have answer choice B ecosystem. Well the ecosystem is actually very similar to bio, however it involves the idiotic plus the biotic factors. So it actually involves the animals and things like this. Remember in the question we're talking about the typical environment that only these organisms are going to be living in. We're not talking about any a biotic factors. So we're going to cancel this out as well. Then we have answer choice deed the niche. The niche is a particular role that an organism is going to be playing in an ecosystem. Remember that here we're not talking about the role we're talking about the typical environment. So this is an incorrect answer choice as well. And we will cancel it out. And this all leaves us with habitat and these habitats are the typical environments or the areas that an organism may live in. For example, they can be forest, they can be the c use the typical place that you will find these organisms because of this answer choice, c habitat is going to be the final answer to your question. I really hope this helped you, and I hope to see you on the next one.
