Blood circulates to provide nutrients and remove wastes in body tissues.
I don't know either!
Our bodies absorb nutrients from the food we eat through a process called digestion. When we eat, our digestive system breaks down the food into smaller molecules that can be absorbed by the intestines. These nutrients are then transported through the bloodstream to different parts of the body where they are used for energy, growth, and repair.
your bodies need nutrients to give us energy and help us grow
No, sloths do not have pouches like some other marsupials such as kangaroos. Sloths carry their young by holding them close to their bodies or clinging to them while moving through the trees.
Nudibranchs do not have a circulatory system like vertebrates do. Instead, they rely on simple diffusion to distribute nutrients and gases throughout their bodies. This passive process involves the movement of substances across cell membranes and relies on the concentration gradient for transport.
Blackworms move food and oxygen through their bodies using a process called diffusion. Nutrients and oxygen are absorbed by the body wall of the worm directly from the environment and are distributed to the cells through the circulatory system. Waste products are also eliminated from the body through diffusion.
The heart beats faster in smaller organisms because they have a higher metabolic rate and need more oxygen and nutrients to sustain their bodies compared to larger organisms. This results in a faster heart rate to circulate blood efficiently.
Organisms with porous bodies belong to the phylum Porifera, commonly known as sponges. Sponges are aquatic animals that lack tissue layers and have a simple body plan with numerous pores to allow water to circulate through their bodies for feeding and respiration. They are considered one of the simplest forms of multicellular animals.

Everything needs some sort of nutrients to live. Fungi get their nutrients from photosynthesis, plants do the same and obtain it from the roots, animals obtain their nutrients from eating plants, and other animals.
