Why are decomposers and detritivores essential parts of all food webs?

Answer: Detritivores improve the nutritional value and the texture of the soil: This makes the soil productive to plant life which translates to availability of food for the herbivores and carnivores like human beings. They however do not complete the energy cycle as their wastes are energy products that need to be decayed.

Decomposers help in converting the leftovers of animals and plants to useful substances for other living organisms. They are mainly bacteria and fungi. Have you ever wondered what would happen if the decomposers and consumers were not in the ecosystem?

Detritivores play a very important in the cycle as they are the consumers of dead leaves, old skin, carcasses and manure. They include millipedes, earthworms and slugs that feed on dead plants and animals but leave some parts and their feces that are converted to energy by the decomposers. Players in the energy cycle function hand in hand, a decomposer is found at the lowest part of the cycle as it deals with the remains. They complete the energy cycle. The roles of the decomposers and detritivores almost coincide.

Hope this helps !!! Good luck !!! ;)

Which of the following statements is correct? a)All animals share a common ancestor. b)Sponges are diploblastic animals. c)Eumet

Alecsey [184]

All animals share a common ancestor.

Explanation:

According to various phylogenetic gene sequence analysis, there are various evidences that proved all animals originated from a common ancestor.

Initially, it was stated that all organisms descended from a single cell which then gave rise to multicellular organisms. Organisms that descend from a common ancestor are closely related and grouped.

The lineage of the common ancestor can be traced in the neoproterozoic era.

The last common ancestor or the basal animal was sea sponge according to some researchers. The last universal common ancestor is called as the concestor.

A star appears to be red in the night sky. Is the star traveling toward the earth or away from the earth? How do we know this? (

neonofarm [45]

Answer:

The star is travelling away from the earth.

Explanation:

A star’s temperature largely determines its color. Stars with higher temperature have a bluish color and stars with low temperature appear red in color. But the color of star that we observe from the earth is different from its actual color.

This variation in color is due to Doppler effect. When the movement of a star is towards the earth the frequency shifts to the higher frequency region and when the movement is away from the earth the frequency of the light emitted will shift to the lower frequency region. Color of light depends on the frequency. 

The color corresponding to the lower frequency region is red and color corresponding to high frequency region is blue. So when the star moves away from the earth it appears red in color.
