Answer:
The correct answer is - option B. it increases the amount of genetic variation in the species.
Explanation:
Meiosis is a type of cell division that takes place in sex cells or reproductive cells. There is crossing over takes place which is a process where the genetic exchange of chromosomes occurs between non-sister chromatids of homologous chromosomes.
The crossing over leads to the new genetic combinations of genetic material which result in the genetic variation in species. This variation plays a role in the natural selection and evolution of species.
Answer:
True
Explanation:
Animals are mulicellural meaning have many cells
Answer:
1: Organisms that make energy are called producers.
Producers are the autotrophic or chemotrophic organisms which are capable of synthesizing their food either by photosynthesis or by chemosynthesis. In the process of photosynthesis organisms use sunlight as a source of energy to convert water and carbon dioxide into carbohydrates and oxygen. Also some simple organisms use chemical energy obtained by chemical inorganic substances and convert them as organic chemical substances to obtain them as food.
2: A decomposer recycles matter back into the food web and biogeochemical cycles.
A decomposer is an organic which feed upon dead decaying organic matter generated after the death of plants and animals. This process results in the simplification of organic matter into simpler substances which are again absorbed by the plants through soil.
3. The sun is the source of energy. The light energy from sun is converted into chemical energy in the form of food by the producers like plants.
4. The autotrophs are found at the base of a food pyramid.
The autotrophs are called as producers because they are capable of synthesizing their own food by the process of photosynthesis . The diversity of producers in nature is more as compared to other organisms therefore, it lies at the base of the food chain.
Explanation:
Answer:Limiting factor is a factor which can limit the abundance, distribution of the species in an ecosystem this can be a resource, predator or natural disaster. The black swallowtail butterfly feeds on endangered plant named Candy's dropwort. If the plants continue to decrease the population of black swallowtail butterly will also decrease as decrease in the plant population will act as a limiting factor for the growth of butterfly population.
