Coal
Coal is a combustible black rock that is formed from prehistoric plant remains. Coal is formed from the anaerobic decomposition of dead plant matter such as trees, ferns, mosses and other marsh plants that grew on the earth surface over millions of years ago. Coal is composed largely of carbon and is usually burned as a fuel.
Probably because of history relation.
<h2>Competitive exclusion principle.</h2>
Explanation:
The fundamental and realized niches of B. balanoides are identical, but the fundamental and realized niches of C. stellatus are different.
All the possible combination of resources and condition under which a species can grow, survive and reproduce is called its fundamental niche. Whereas, the more limited set of resources and condition under which a species can grow, survive and reproduce in the presence of competitors and predators is termed as its realized niche.
Competitive exclusion principle states that if two competing species coexist in a stable, homogeneous environment, then they do so as a result of differentiation in their realized niche.
<em>B. balanoides</em> can use a wider range of resources than<em> C. stellatus </em>because its fundamental and realized niches are identical . Hence thrives to exclude C.stellatus.
<span>B. A secondary consumer that obtains its energy from the consumption of animals.
The red-tailed hawk is a secondary consumer because it feeds itself on primary consumers (those that eat plants, herbivores). Secondary consumers, by definition, </span><span>obtain their energy from eating other animals. Secondary consumers are also usually the ones that stand on the second and above rows of a food chain, being the plants at the bottom and the primary consumers just above the plants.</span>
Answer:
A. Sensation
Explanation:
- <em>A sensation</em> is a mental process (like hearing, seeing or smelling) resulting from the immediate external stimulation of a sense organ often as distinguished from a conscious awareness of the sensory process, it's a physical feeling or perception resulting from something that happens to or come into contact with the body. Considering the example given the freshly cut grass, gentle breeze and sound of children laughing are the physical feelings stimulating your nose, skin, and ears.
- <em>Selective attention</em> is focusing on a particular object in the environment for a certain period, in your example, the subject is not specifically focusing on one thing at the time.
- <em>Sensory adaption</em> is the reduction in sensitivity to a stimulus after constant exposure to it, in this case, the subject is nos experiencing awareness of a constant stimulus.
- <em>Cognition</em> is the process of acquiring knowledge and understanding through thought, experience, and the senses. In your example, the data obtained by the subject is still not processed.
