Environmental conservation protects wildlife and promotes biodiversity. Maintaining a healthy and functional ecosystem helps prevent the extinction of certain animal species. If the environment is destroyed, some animals are forced out of their habitat, making it hard for them to survive elsewhere.
The correct option is this: PIONEER ORGANISMS MOVE INTO NEW COMMUNITIES FIRST.
Ecological succession refers to the process of change that occur to the species in a given community over a period of time. Succession is caused by change in the environment and its effects on the living organisms that are living there. There are two basic type of ecological succession, these are primary and secondary ecological succession.
Primary ecological succession typically occur in an environment that is devoid of any form of vegetation or life form; it is usually a bare land that lack soils that are needed for plants' growth. The first set of plant that grow in this kind of environment are called pioneer species. Such plant usually have ability to survive in harsh environment. Example of such plant is ferns. Primary succession is very slow and can take hundreds of years.
Secondary succession usually occur as a result of an event which reduce an established ecosystem into a smaller population. The event could be a forest fire, flooding, etc. Secondary succession takes place in an environment in which some living organisms are still existing. The process is fast compared to primary succession.
Answer:
c. Evolution
Explanation:
Antibiotics are drugs that fight infections by destroying specific parts of the bacteria that cause them. To survive the attack, some bacteria evolve, adapt and create resistance to medication. Then, this practically immune bacteria to the medicine can spread its "superpower" to the descendants. This is why taking antibiotics without a doctor's request is so dangerous to your health and that of the general population.
1. insulation B. fat cells - it is not uncommon to say that people who weigh a lot generally preserve more heat
2. food supply A. capillaries - they transport food
3. follicle C. hair shaft
4. sweat gland D. cooling - your body cools down when you sweat
5. touch E. nerve endings - nerves help you feel things
The best way is to compare the DNA of the two species. The more nitrogenous bases and amino acids two species have in common, the more closely related they are.
