Cladodes are modified stems. which is their main function? A. Water retention B. Food storage
C. Photosynthesis

Answer:

Drought impacts ecosystem in many different negative ways.

• All biotic factors (that is living organisms) in an ecosystem depend on water.
• It can also lead to losses or destruction of fish and wildlife habitat.
• Lack of food and drinking water for wild animals.
• Increase in disease in wild animals, because of reduced food and water supplies.
• Drought can lead to increases in wildfire and insect outbreaks, local species extinctions, forest diebacks, and altered rates of carbon, nutrient, and water cycling – all of which can have real consequences for ecosystems and human communities alike

• Plants and animals depend on water, just like people. When a drought occurs, their food supply can shrink and their habitat can be damaged.
• Sometimes the damage is only temporary and their habitat and food supply return to normal when the drought is over.

Answer: There will be adjustment on water loss mechanisms and development of water conservation

Explanation:

Metabolites are the different kinds of the substances which are essential to metabolism of the organism.

Metabolites produced by the plants can be categorized into the primary metabolites and the secondary metabolites.

The primary metabolites have important role in survival of plant and play an active role in the respiration and the photosynthesis.

On the other hand, the secondary metabolites are not involved in normal growth and the development of plant. Although absence of these type of metabolites can lead to impairment of survivability of plant in long run.

Secondary metabolites are produced mostly by the plants for the defense purposes. They include steroids, alkaloids, phenolics, essential oils, resins, tannins, lignins, flavonoids, etc.
