DNA make up the chromosomes that are then passed off to the parent's offspring. The DNA is in the chromosomes and it translates the genes to determine traits
Examples of biting and chewing pests are snails, slugs, caterpillar, Helicoverpa, diamond black moth, beetles , termites, leaf worms, grass hoppers etc.
Examples of piercing insects are lace bugs, aphids, white flies, glassy winged sharp shooter, false chinch bugs, Bargrada bug, mealy bug, Eugenia psyllid, Pittosporum psyllid, Tipu psyllid etc.
<u>Explanation:</u>
Pests that affect crops have different feeding habits. Some pests belong to the type biting and chewing pests. These pests bite into the plant parts and chew them. This will leave circular holes in the leaves and semicircular holes in the leaf edges.
Piercing and sucking insects pierce into the plant parts and suck the sap. Removal of sap turns the plants yellow, and wilted. The growth might get stunted and in severe cases the plant may die off.

Explanation:
their roots respond positively, growing down, into the soil, and their stems respond negatively, growing upward, to reach the sunlight.
I have seen several people get this wrong a lot. Cilia, which is more associated with cell movement is not so with Paramecium. To capture food, a Paramecium uses its cilia to capture food and transport it to the "mouth"
Foxes eat a variety of animals, which includes caterpillars. On the contrary, most caterpillars eat only plants. In any ecosystem, you always have a larger number of plants than the number of animals which eat plants, and you have an even smaller number of animals which eat other animals. That is related to the flow of energy in the ecosystem:
1) The sun provides solar energy and plants use part of it for photosyntesis. Later, that energy will be stored by the plant as chemical energy.
2) Herbivore animals eat some of the plants, in order to use their chemical energy. Animals can never eat all plants because that would lead to extinction. Besides, part of the chemical energy of the plants they have eaten is wasted because it converts into heat energy.
3) Carnivore animals eat herbivore animals. Same conclusion, they can never eat all herbivore animals and they cannot use all their energy. If they are ominvore, they are sort of sharing the plants with herbivores, so herbivores can eat less plants.
Malnutrition reduces the population, so less food leads to smaller population.
