Look it up if you are stressing.
The oxygen that goes through alveoli and diffuses into blood capillaries. The oxygenated blood goes though aorta and is pumped by the heart and goes out through the vena cava to be distributed to the whole body. the deoxygenated blood comes back to the heart from the body and is pumped back towards the lungs. the carbon dioxide diffuses out of the blood capillaries and goes out of the body.
Answer:
herbivores
Explanation:
because herbivores breakdown animal and plant material
People sleep (usually) at night, and dogs and cats doze pretty much whenever they can. But how about other living things, like plants? Whether or not those tulips turn in at the end of the day depends on whom you ask—and how you define sleep.
Plants don’t have a central nervous system, which is an essential regulator of sleep in humans. But they do tune themselves to a 24-hour circadian rhythm, just like you. And they do shut down certain processes, like photosynthesis, when the sun goes down, shifting their focus instead to delivering glucose (sugar) throughout the plant. Some plants, including the aptly named morning glory, also close their blooms when the sun goes down.
Sunlight is a key trigger for humans to know what time to sleep and when to be awake. And the same is true of plants. While light and dark tell your body when to produce the hormone melatonin, which cues your body to feel sleepy, light and dark triggers tell plants when to produce the hormone auxin, which controls growth and development.
Plants may not be able to get up and hunt for food (or grocery shop, or call for takeout, for that matter!), but they do move in small ways to maximize their exposure to energy-giving sunlight. During the day, they soak up the sun in order to make energy through photosynthesis, a plant’s version of eating. Then, at night, they turn their attention to metabolizing the energy that they’ve taken in and using it to grow. So maybe you should be saying “goodnight” to your garden when you turn out the lights! hope this helps
Yes because we use the sun light as a way to grow crops for one so no one would be getting any food and plant life would never grow and would die so we wouldn't be getting Air as well because trees and plants make oxygen for us
