A biome refers to a community of animals and plants, which exhibit communal features for the surroundings they prevail in. They can be found over an array of continents.

Biomes refer to the different biological communities, which have got produced in reply to a shared physical climate. A biome is a larger term than habitat; any biome can include numerous habitats.

In biomes, precipitation and temperature are the two main elements, which influence vegetation.

Which form of succession replaces an existing system after a calamity?

lina2011 [118]

Answer:

Secondary succession

Explanation:

Ecological succession is the term used to describe any series of change in the composition of an ecosystem over a particular period of time. Ecological succession is made up of two types viz: primary succession and secondary succession.

Primary succession involves the formation of a brand new ecosystem by the colonization of a barren area of land e.g bare rock, where no life existed. Secondary succession, on the other hand, is the recolonization of an area by a new set of organisms because the previously existing organisms have been wiped out by certain disasters e.g fire outbreak, hurricanes etc. In secondary succession, there is soil, which makes it possible for new organisms to sprout quickly after the calamity.

Example of secondary succession is when a fire outbreak burns the organisms in a community, allowing the root of grasses to sprout after.

In garden pea plants, purple flowers (P) are dominant to white flowers (p), and full pod shape (F) is dominant to constricted po

kifflom [539]

Answer:

The phenotypes are as follows

Purple, full- 9

Purple, constricted- 3

White, full- 3

White, constricted- 1

Genotype of parents are PpFf, each produce the following gametes: PF, Pf, pF and pf.

Explanation:

This is a dihybrid cross involving two distinct genes. One coding for flower color and the other for pod shape. The allele for purple color (P) is dominant over the allele for white color (p) while the allele for full pod (F) is dominant over the allele for constricted pod (f).

In a cross between two heterozygote parents i.e. PpFf × PpFf, each parent will produce the following gametes: PF, Pf, pF and pf. Using these gametes in a punnet square (see attached image) the following 16 offsprings will be produced in a phenotypic ratio: 9:3:3:1

Purple color, full pod- 9

Purple color, constricted pod- 3

White flower, full pod- 3

White flower, constricted pod- 1
