Where does energy first come into an ecosystem?

Biology
1 answer:
Zinaida [17]3 years ago
5 0

Answer:B. Sunlight provides energy to producers

Explanation: photoautotrophs (plants) produce energy from sunlight by photosynthesis. This is the only energy production based on an external source of energy. Plants, whether alive or dead, are consumed by heterotrophs - bacteria, fungi and animals. The nutrients and energy from dead heterotrophs (and some live ones) are recycled by both autotrophs and heterotrophs.

A grassland is experiencing a severe drought. The lack of rain is causing the grass to die and the ponds and creeks to dry up.
dusya [7]

The population of fish will decrease.

The population of grazing animals will decrease.

<h3>What is drought?</h3>

A drought is a prolonged period without enough precipitation/water to support people, animals or crops.

With less water, fish and other creatures have fewer places to dwell, swim, and evade predators. In the near run, shrinking streams and lakes necessarily result in fewer fish. Drought conditions can cause water temperatures to rise, affecting cold-water species such as native trout.

The population of grazing animals would decrease as the grass is a food source and without their food source, there would be no source of staying meaning that they would result to finding new food sources through migration likely.

What fraction of offspring of the cross AaBb × AaBb would be homozygous for both the dominant alleles, assuming that they are on
Veseljchak [2.6K]

Answer:

A. 1/16

Explanation:

If we break the dihybrid cross of AaBb X AaBb into individual monohybrid crosses:

Aa X Aa :

     A    a

A  AA Aa

a  Aa   aa

1/4 of the progeny will be homozygous for dominant allele (AA)

Similarly, in cross Bb X Bb 1/4 of the progeny will be homozygous for dominant allele (BB)

Hence, in cross AaBb X AaBb:

1/4 * 1/4 = 1/16 will be homozygous for both the dominant alleles.
