What do you mean by food chain?

In ecology, the food chain is the flow of substance and energy from one organism to another in the form of food.

A process cycle from producer to consumer to decomposer is referred to as a food chain.

Plants, herbivores, omnivores, and carnivores all exist. Beginning with plants, moving on to herbivorous insect, spiders, a small bird, a snake, a hawk, a fox, and a lion When a person passed away, a hyena would consume their body. When the hyena passed away, the body would disintegrate, becoming food for worms, and then become fertilizer for plants. so according to 10 percent rule, zooplankton get 5000 j of energy from phytoplanktons.

The food chain's cycle will then repeat itself time and time again.

How does cladistics reconstruct phylogenies?

Answers

Cladistics reconstructs phylogenies by considering shared derived characters between taxonomic groups and the maximum parsimony criterium.

What is the cladistic analysis?

Cladistics evaluate the relationship between different taxa according to shared characters.

The cladistic analysis follows the maximum parsimony criterium.

Explains the character state from the point of view of the fewest changes through history. Explains evolution with the minimal amount of evolutive changes.

It recognizes the monophyletic groups as natural groups. These groups are the clades, and their classification -sequencing- represents their phylogeny.

The sequencing term refers to lists of groups according to their relationship and their shared traits. One group is the sister group of the following one.

Cladistics uses cladograms to represent the common ancestral relationships and the emergence of different characters among the involved groups.

So the cladogram represents the relationship between taxonomic groups according to a derived character.

The derived character is any new trait that a group transmits to its descendants.

Through evolution, the characters change, and new changes are added. When referring to a derived character, we mean that all the subsequent groups in the cladogram carry and share the trait.

According to this framework, cladistics reconstructs phylogenies by considering shared derived characters and the maximum parsimony criterium.

Which concept is part of the theory of evolution by natural selection

Answers

Answer:

New generations are better suited to survive than previous generations.

Explanation:

Darwin's evolutionary theory states that evolution is the slow process through which organisms change over time. Natural selection is the process by which evolution takes place. Variation in organisms, some of which offers an adaptive benefit, may be passed down from generation to generation. Better suited organisms will have a higher probability of surviving and procreating, and they will also pass on these phenotypic modifications to the offspring. Evolution is a long, protracted process because these phenotypic changes occur gradually across generations at the species level. As a result, it is anticipated that future generations would be better adapted to endure in the same environmental circumstances.

The correct option is (c)New inorganic and organic substances are created from energy in the process that occurs in the cells of both self-feeders and other-feeders.

What are Autotrophs(self-feeders) and heterotrophs(other-feeders)?

Autotrophs (self-feeders) are organisms that synthesize the biological molecules necessary for life support and digest inorganic substances from their environment using an external energy source. This kind of nutrition is found in plants that prepare their food through photosynthesis.

An organism that consumes other species in a food chain is known as a heterotroph (other-feeders). Heterotrophs cannot transform inorganic materials into organic ones, in contrast to autotrophs. They have to rely on a source of organic carbon that was once a part of a living thing. Heterotrophs depend on autotrophs either directly or indirectly for nutrients and food energy. This kind of nourishment is present in parasites, bacteria, fungi, yeast, humans, and other animals.

What are some possible benefits and dangers if the DNA is used to create a mutant form of the organism?

Answers

Explanation:

The majority of mutations have neither negative nor positive effects on the organism in which they occur. These mutations are called neutral mutations. Examples include silent point mutations. They are neutral because they do not change the amino acids in the proteins they encode.

Many other mutations have no effect on the organism because they are repaired beforeprotein synthesis occurs. Cells have multiple repair mechanisms to fix mutations in DNA. One way DNA can be repaired is illustrated in Figure below. If a cell’s DNA is permanently damaged and cannot be repaired, the cell is likely to be prevented from dividing.
