Answer:

2.  Aphids damage roses by piercing the plant tissue and then out vital plant juices.

importance: First, they remove plant sap from phloem sieve elements, which weaken the plants resulting in lower quality and quantity of fruit. Heavy infestations can result in plant death.

3.:Like all plants, trees convert sunlight energy into sugars (chemical energy) through the process of photosynthesis. Trees compete with each other and with other plants for the sunlight available on a site. When trees get over- topped and shaded by others, their access to sunlight is reduced

Grass roots in the full sun occupy much more soil than tree roots, which can be a problem if planting young trees. But under mature trees, the grass is thinner and the roots less dense, so they compete poorly with these tree roots.

Photoautotrophic organisms (plants, algae, cyanobacteria) obtain energy by converting sunlight, carbon dioxide, and water into organic molecules, a process called photosynthesis. Photoautotrophs, also called primary producers, compete for light and water.
