Question

in a forest, why might two different species of plants compete for the same spot?
one plant wants to eat the other plant.
they are trying to help the animals.
they both need the same sunlight and water.
they want to share the space

Explanation:

Plant species compete when they rely on the same limited resources in an ecosystem. Sunlight, water, and soil nutrients are critical, limited resources for plants in a forest, so overlapping need for these drives competition. The other options are incorrect: plants do not eat other plants in this context, they do not compete to help animals, and they do not compete to share resources.

Answer:

They both need the same sunlight and water.
