Why are the first plants to appear in primary ecological succession so small

Biology
1 answer:
Ede4ka [16]3 years ago
5 0

Answer:

They are small because they are growing on bare surfaces, not even soil, so they're just growing on abiotic things like rocks, so the first plants are more like weeds, lichens, small mosses, etc... because these are the only types of plants suited to turn this habitat back into its original climax community through means like nitrogen fixation. Also, because there's probably no to little nutrients there which can cause nutrients to be a limiting factor to their growth and cause them to be stunted. Need me to elaborate more?

Natali [406]

The more numbers of the homologous structure, the more likely they have recently shared a common ancestor.

Explanation:

Homologous organs are seen in species that are very close to each other which are more related with each other in terms of evolution. For example, a bird is more close to each man than a fish, so do share more homologous organs common to man than fishes do. Examples of the homologous organs are hands of human and wings of birds. They have same basic structure like skeletal structure which is humerus, radius, ulna, carpals, metacarpals and phalanges. They are similar in structure but have different functions like flying in birds and gathering food in humans.
