The flow of energy in an ecosystem is best
melamori03 [73]
The flow of energy in an ecosystem is best described as energy moving in one direction from the sun to the producers then to the consumers. 

Explanation; 
Energy flow is the amount of energy that moves through successive trophic levels of a food chain in an ecosystem. Ecosystem maintain themselves by cycling energy and nutrients.
The energy from sunlight is taken up by producers which use it to produce organic compounds through photosynthesis. The energy is then passed successively to the trophic levels, that is from the producers to the consumers ( primary, secondary, tertiary and quotienary consumers). During this transfer some energy is lost at each trophic level in form of heat.

A species of fly has two alleles for the length of their legs. The allele for long
postnew [5]

Answer:

According to Hardy Weinberg law (p+q)2=1 where p is fequency of one allele and q is the frequency of another allele.

Explanation:

According the question

 q represent the short legs and 33 of 100 organism have short legs.

    As a result the frequency of q with respect to the 100 organism is 33/100

                                                                                                                   =0.33

Therefore q=0.33

     we all know that

                   (p+q)2=1

              ∴  p+q= 1

              ∴  p=1-q

                   p= 1-0.33

                    p=0.67

The frequency of p is 0.67

Energy in communities-What percentage of energy is used and left over and why is this important for our environment?
maw [93]

Answer:All energy sources have some impact on our environment. Fossil fuels—coal, oil, and natural gas—do substantially more harm than renewable energy sources by most measures, including air and water pollution, damage to public health, wildlife and habitat loss, water use, land use, and global warming emissions.

Explanation:It becomes clear that for more than 45 percent of respondents, solar energy was the most environmentally friendly energy source. The energy generated by the wind was also a considered to be pro-environment by almost 24 percent of the respondents.
