Describe the roles of light, carbon dioxide, and water in the production of foox and oxygen

Light is absorbed in the plant's leaves. Carbon dioxide is taken in through the stomata. Water is absorbed into the xylem through the roots carried through the plant to the leaves.

Explanation: Then the plant uses all of these ingredients to produce food and oxygen. The food is carried throughout the phloem  and is then used to grow and develop while the oxygen is released out of the stomata.

genetic variation will increase because of a new habitat and food source.

explanation:

answer: grassland biomes are closer to the equator and receive more rain.

grasslands are biomes that are dominated by grasses rather shrubs and trees. savanna are biomes that exhibit grasses, shrubs and small tree as vegetation. grasslands are located near the equator of the earth. these are found in north america. savanna biomes are found in africa, south america, australia and india. grassland exhibit moderate climatic conditions, it receives   amount of rainfall higher than savanna.   therefore, savanna exhibit dry and hot climatic conditions.
