Answer 2

Answer:

1 How do worms breathe? Through their skin – but only if it's kept moist. A worm's skin is covered in mucus that helps them absorb oxygen. This is why they prefer to stay underground and come to the surface after rain. 2 For insects, respiration is separate from the circulatory system. Oxygen and carbon dioxide gases are exchanged through a network of tubes called tracheae. Instead of nostrils, insects breathe through openings in the thorax and abdomen called spiracles.

Explanation:

3 All living things need food to stay alive, grow, and get energy. Nutrition is the process by which living things get or make food. All animals get food by eating other living things. Herbivores eat plants, while carnivores eat other animals. 4 Animals move for a variety of reasons, such as to find food, a mate, a suitable microhabitat, or to escape predators. For many animals, the ability to move is essential for survival and, as a result, natural selection has shaped the locomotion methods and mechanisms used by moving organisms. 5 Plants move from place to place as seeds. Plants bend towards light by growth. ... The cell contents of plants are in continual movement - often in a circular motion. Some desert plants roll into a ball and blow to another place where they settle and take root again.
