A group of trees are on a hillside

The trees will most likely compete with one another for-
A.carbon dioxide
B.soil
C.water
D.oxygen
I think it's C
I know that plants take in carbon dioxide and give out oxygen

I agree.

Ok, thanks

You are correct! The group of trees on a hillside is most likely to compete with one another for water. To determine this, it helps to understand the needs of trees.

Trees require water for various essential processes, such as photosynthesis, nutrient uptake from the soil, and adequate hydration of their cells. On a hillside, water tends to flow downward, which means that trees at the higher elevation may receive a higher amount of water compared to those at lower elevations.

As a result, the trees lower on the hillside may face more competition for water. They will have to compete with the trees above them to absorb water from the soil and ensure their survival and growth.

While carbon dioxide is indeed necessary for photosynthesis, it is generally abundant in the atmosphere, so it is not a limited resource that trees would typically compete for. Similarly, oxygen is a product of photosynthesis, and trees do not directly compete for it.

Soil is essential for trees to anchor their roots and provide nutrients. However, the competition for soil might not be as significant as for water since trees can spread their roots across a wider area to access nutrients. In contrast, water is more likely to be a limited resource that trees will compete for.

To summarize, in the given scenario, the trees on the hillside are most likely to compete with one another for water (option C) rather than carbon dioxide (option A), soil (option B), or oxygen (option D).
