jarptica [38.1K]

Answer:

Correct answer is A. "making future predictions about plant behavior "

Explanation:

The most important part of the question is "overcrowded area" which leads to the future concerned scenario of modern societies. We know that, in future, the supply of resources/nutrients will be limited and thus we want to develop sustainable practices. For this, scientists often carry out the experiments where the organisms are forced to live/grow in a crowded area and then we understand how each individual responds in the presence of limited resource supply. In this experiment, I perceive that the scientist is doing a similar kind of study for a specific plant which will help him assess the future concerns of growth and development for that species as well as its interaction with the environment.

WILL GIVE BRAINLIST!!!!! what are 3 ways that animals and plants can erode rocks in different locations?
Llana [10]

Answer:

Hope this Helped :)

Explanation:

1.Biological weathering-Plants and animals release acid forming chemicals that cause weathering and also contribute to the breaking down of rocks and landforms.

2.Plants change Earth’s surface through weathering and erosion.They take minerals from  the rock. This is a type of weathering, and it weakens the rock. Eventually the  surface of the rock starts to break down and become soil.

3.As larger plants like trees start to grow in a rocky area, their roots

grow into the small cracks in the rock. Slowly, as the tree grows, its roots break the rock apart. This forms more soil and makes it easier for other plants to grow there as well.

4.When too many animals live in one place,  they tend to eat and trample all the plants. Without the plants to protect the soil, it is  more likely to be eroded by wind and water.
