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.
Carbon is so important because it’s how living things breath

Answer:
harmful effect and no effect

Harmful effect: an example of harmful effects would be down-syndrome (where you have 3 21-chromosomes and you are only supposed to have 2)
Traits included physical features such as flower color. Today, these factors are called <u>alleles</u>. Mendel developed the hypothesis that some factors could be dominant, while others were <u>recessive</u>. According to his theory, a dominant factor is expressed when <u>only one factor is presen</u>t in the offspring. On the other hand, a <u>recessive</u> factor expresses its <u>phenotype</u> when <u>both factors are present</u> in the offspring. Today, the term<u> genotype </u>refers to the combination of factors possessed by an organism.
- alleles
- recessive
- only one factor is present
- recessive
- phenotype
- both factors are present
