Which statement describes an important role of carbon dioxide in Earth's atmosphere?
Animals breathe carbon dioxide.
O Plants use carbon dioxide to make food.
O Carbon dioxido helps animals make proteins.
Carbon dioxide forms clouds that produce rain

Answers

Answer:Plants use carbon dioxide to make food

Explanation: Carbon-dioxide plays a very important role in sustaining life on Earth.

Plants use carbon-dioxide and water for photosynthesis in presence of sunlight and chlorophyll to produce food and oxygen.

CO₂ + H₂O →  O₂ + glucose (food)

This food is consumed by the animals and oxygen is used for respiration. Animals use energy from the food to do work and exhale back carbon-dioxide.

Plants using the CAM pathway occur in many locations but are most common in very arid locations, such as deserts. What deserts occur in North America and where are these deserts located?

Answers

The desert that occurs in North America is the Great Basin Desert and it is located at Nevada of North America.

CAM pathway, which is also called Crassulacean Acid Metabolism, is a pathway that involves carbon fixation that occurs in plants growing in arid areas.

With this pathway these plants are able to photosynthesize during the day, but only exchange gases at night.

An arid habitat is an environment that is characterized by extreme lack of water, example is the desert.

In North America, the desert that occurs there is the Great Basin Desert. It spreads into different states which include:

NevadaWestern Utah, Eastern California, andIdaho.

But the major part of Nevada is occupied by the Great Basin Desert.

Explanation:

Help please and are the ones that already answered to are correct ?

Answers

Yes, all of your answers are correct except for number 12. Instead I would say a food chain outlines who eats whom but a food web is all of the food chains in an ecosystem.

Primary consumers are basically herbivores, such as squirrels, rabbits, crickets, etc.

Secondary consumers are carnivores/omnivores, animals that eat other animals such as foxes, snakes, and owls.

Higher order consumers are animals that can eat more things, like humans for example, because we eat animals that are bigger than us like cows but we also eat plants.

Omnivores are animals that eat meat and plants, such as humans and mice because according to your food web, mice also eat meat.

I can’t see the picture very well because it’s blurry, but i think the owl eats some kind of animal that looks like a frog and snakes, so if the owl is removed the frog animal thing and snakes would increase.

for the last question, i would say
