Some plants like sugar cane and cacti use different photosynthetic pathways known as ___ plants so that they can keep their stomata closed on hot days in order to conserve water.

C4 and CAM plants

Explanation:

The plants when faces the high temperature and dry condition, then in order to prevent water loss they close the stomata which increases the oxygen in the plants.

This causes the Rubisco to bind oxygen as a result of which the plants undergo wasteful photo-respiration.In order to void such a wasteful process, the plants separate the photosynthesis process spatially and temporally. Such adapted plants are known as the C4 and CAM plants.

Thus, C4 and CAM plant is correct.

they dont have any evidence

b. climate change will cause an increase in biodiversity of all ecosystems.

hope this
