Question

what happens to animals that are deprived of oxygen? *
a they will produce more glucose.
b they will stop photosynthesis.
c they cannot do cellular respiration and will die.
d they will grow faster.
how would dust blocking the sun affect plants and animals? *
a it would increase oxygen, making plants grow.
b it would stop photosynthesis, reducing oxygen and food.
c it would help cellular respiration happen faster.
d it would make more carbon dioxide available.

Explanation:

For the first question, animals need oxygen for cellular respiration to produce energy. Without oxygen, they cannot perform this vital process and will die. For the second question, plants need sunlight for photosynthesis. Dust blocking the sun would prevent photosynthesis, reducing the production of oxygen and food sources for plants and animals.

Answer:

1. C. They cannot do cellular respiration and will die.
2. B. It would stop photosynthesis, reducing oxygen and food.
