<u>Answer 1</u>- Earthworms are decomposers. They decompose the organic matter and convert the complex substances into simpler digested molecules. These molecules are released into the soil by the feces of earthworms. This way earthworms replenish the soil fertility and return the nutrients back to the ecosystem.

<u>Answer 2</u>- Food chain is a series in which organisms are placed in a systematic order of flow of energy and nutrients. An example of food chain with earthworm is shown in image shared below.

Mutations are rare and occur because of?

kodGreya [7K]

Mutations result from an error in DNA replication, should it be from an alien source (like radiation) or simply a mistake in replication. Migration of organisms to a new population would alter the DNA by adding new genes, but it would not mutate them.

Insects and millipedes were among the very first terrestrial animals. Hypothesize what characteristics of their aquatic ancestor

alukav5142 [94]

Answer:

Preadaptations like tegument and body segmentation could have been used by insects and millipedes to survive in terrestrial habitats.

Explanation:

As crustaceans, millipedes and insects have a protective, hard tegument, which surface is frequently smooth. Some groups can also present spines, bristles, or tubercles. The tegument protects the animals against harmful stimuli of different nature, such as mechanic, thermal, chemical, etc. It is also an effective barrier against pathogen microorganisms and excessive dehydration. In groups like crustaceans and insects, as the external layer gets hard, the tegument constitutes an important support organ. It is composed of a simple, cubic epithelium called hypodermis, and secretes exoskeleton, which is composed of chitin and can also be shaped by calcareous impregnations. Chitin is an impermeable, light y hard substance, that allows life on land without dehydration. Segmentation (repetition of identical anatomical units) is another characteristic in these groups that have helped to domain terrestrial habitats. It seems like segmentation is highly advantageous from an evolution point of view because it is much easier to adapt each segment separately to environmental pressures, responding to different necessities, than adapting the whole body to it, developing a new organ for each necessity. Also, it is a strategy to defend themselves from predators by rolling up.
