Answer: The given statement is True.
Food chain can be described as the sequence of transfer of energy and matter among different organisms present within an ecosystem.
It starts with producers ( occupying the first trophic level), which are consumed by consumers in a successive manner ( primary consumer→ secondary consumers→ tertiary consumer or decomposers).
Therefore, producers are beginning link in a food chain whereas decomposers occupy the last level in a food chain.
Answer:
<em>The correct option is D) immigration</em>
Explanation:
Immigration can be described as the movement of an organism to another place for living. As the scenario in the question tells, the population of the endangered Philippine eagle could be seen only in one place hence we can say that the immigration rate of these organisms was zero because they could not be seen in any other place.
Other option, like option B, cannot be correct because mortality refers to the death rate and obviously many organisms of the species died due to which it became endangered.
Clouds can block light and heat from the Sun, making Earth's temperature cooler. You've probably noticed this kind of cooldown on a cloudy day. However, some heat from the Sun does get down to Earth. Clouds can trap that heat from the Sun.
