7. Which of the following is a living renewable resource? sunlight ,warer ,trees ,wind

You were right the first time. The answer is trees!

Explanation:

The question asks which of the following is a living renewable resource. The keyword is the word living that is right before renewable resource. A living renewable resource is not only a resource that naturally replenishes itself, but a living renewable resource produces more of its kind while it lives and then it dies. For example, a plant is grown from a seed and produces more seeds before eventually dying or a hen that lays eggs which hatch more chickens before she finally becomes someone's dinner. These are the living resources that set them apart from the others. Sunlight, water, and wind are all renewable resources, but unlike trees, they are not living.

one is through turgidity. this occurs before ground tissue ( collenchyma

and sclerenchyma cells) become well

developed to give structural support to the plant as it grows bigger. the xylem

tissue (composed of rigid tissue) of the young

plant render this support and also maintaining osmotic turgidity of the surrounding

plant cells.
