Some <u>birds</u> are both primary consumers and secondary consumers.
<u>Explanation:</u>
Primary consumers are the class of animals that are feeding upon the producers as their primary food. Secondary consumers are the class of animals that are feeding upon a primary consumer to feed themselves.
Some of the birds like sparrow, humming birds etc feed on fruits and seeds of plants to maintain their lives. They are thus the primary consumers. Others like eagle, crow eats on flesh of primary consumers. So they are secondary consumers. Thus birds can be both primary consumers and secondary consumers.
Answer:
Yes they are wrong
Explanation:
I've met many people who are the sweetest things but their parents are a different story it all depends on who you are around and what you take in from other.
Some species are able to reproduce at a fast rate, creating large populations that ensure some individuals will survive.
The impact on the human health as we try to stay ahead of the evolutionary process is actually very bad. It is a fact that the humans are living much longer nowadays than ever before, with the main reasons for that being the well developed medicine and healthcare, much better standard of living, and having less riskier jobs. On the other hand, the human health, without being treated, is actually at an all time low. The immune system is much weaker than it has been, with the main reason being the isolation of the outside world and the higher level of hygiene. The allergies are becoming an ever growing problem because of this, as the immune system doesn't even recognize certain outside bodies are they an enemies or not. The constant radiation for numerous sources has caused development of numerous diseases. The old age has increased the percentage of diseases such as cancer, Alzheimer, Parkinson, or sclerosis. The less active life-style and food over saturated with fats and sugars has caused numerous health problems as well. All in all, the human health has become dependent on the pharmacy and its products, and without it it will suffer badly.
Physical differences in beaks of birds would develop as a result of different environmental changes.
<h3>What is Evolution?</h3>
This is described as the process in which heritable characteristics are changed in species over successive generations. This occurs as a result of natural selection in which the traits suitable for survival are passed to the offspring.
This is usually as a result of a change in the environmental factors which ensures that the organisms are able to adapt so as not to die out and go extinct in this type of scenario.
