Answer:
1. Both food chains and food webs show the flow of energy in an ecosystem. However, food chains illustrate one path of energy, while food webs show multiple paths of energy and interactions among food chains.
2. About 90 percent of the energy at each trophic level is lost and not available to the next level. If the producer level has 100 units of energy, then 10 units of energy are available for the primary consumers.
3. Green plants. Just as 90 percent of the energy at each trophic level is lost, the amount of biomass is typically highest at the primary producer level and decreases in higher trophic levels.
4. Energy is lost to the environment in the form of heat.

Got this straight from Penn Foster, After I wrote the answers
<span>Martin Luther King, Jr. believes that we need gadflies
because we need to bring to light issues that need to be resolved especially
when it concerns the violation of people’s rights to be treated equally. Gadflies are those who make a lot of noise
through their speeches and actions that draw people’s attention. Still Dr. King maintains that gadflies should
use their talents to promote non-violent confrontations to resolves issues of
social injustice. These are the people
who speak their mind with such force that others listen even if they think it
doesn’t concern them. More people
gadflies attract, the more attention is given to the issues at hand. By doing
that, it would spur government to do something about it.</span>
