These three
traits definitely standout as a challenge for every living creature in the ecosystem.
In Darwin’s Natural Selection Survival of the fittest: being fit is one
category in order to survive the wild, in other words, being flexible. Reproduction
is battle royale in both humans and animals, even for plants too. Why? Because
the ecosystem changes, the weather changes, the food chain is a combat to chase.
Some can’t even reproduce due to hereditary or physical causes. Energy is as
important as living. If plants can make their own food how about the carnivores
and the omnivores. Food is a challenge. Structure is sustaining the capacity
and ability to hunt and survive. Important and a by-product of obtaining
energy.
Nuclear reactors use hydrogen and they are an up and coming energy source.
There are also hydrogen fuel cells.
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.
Both breathe air. Both can be herbivores, omnivores, or carnivores. Both are warm blooded. Both are animals. Both have an interior skeleton. Both have four limbs. Both have two eyes. Both have large central nervous systems.
