Plant cells have cell wall but animal cells don't have any cell wall.
Answer:
<em>1. They effect crop productivity</em>
As weeds start to grow in the area where the crops were destined to grow, the production of the crops gets lowered.
<em>2. They deplete the crops from nutrition</em>
The weeds will compete with the crop plants for resources such as minerals from the soil.
<em>3. They will deplete water resources</em>
The weeds will compete with the crop plants for water.
<em>4. Sun-light will be depleted</em>
The weeds will complete with the crop plants for sun light.
<em>5. The crop quality will be affected</em>
As the crop plants will be in competition with the weeds, hence their quality will be affected.
6. <em>They can reduce the biodiversity of crop plants.</em>
The inner layer, the dermis, consists of a superficial papillary region of loose, areolar connective tissue, connective tissue and a thicker and deeper reticular region of dense irregular connective tissue connective tissue.
<h3>The layers of the skin</h3>
The skin is the largest peripheral organ that covers the outer layers of the body. It is made up of two layers namely:
- Epidermis: The epidermis is the outer layer and it is made up of stratified squamous epithelium.
- Dermis: The dermis is the inner layer of skin. it is made up of superficial and deep layers.
The superficial layer is made up of papillary region of loose areolar connective tissue which helps to attach epithelial tissue to other underlying tissues.
While the deep layer is made up of dense irregular connective tissue which provides strength, making the skin resistant to tearing by stretching forces from different directions.

After a tornado or a hurricane the local ecosystem will be very damaged, and when the wind stops blowing, or all the water is drained/dried, the ecosystem will start recovering:
- The earth will recover
- Plants will regrow.
- Animals will come back.
- The ecosystem will slowly rebuild.
