Ecological succession a) The first organisms that appear in an area after it has been disturbed
b) The variety of life in an ecosystem
c) A biodiverse community of organisms in an ecosystem many years after a
disturbance
d) Gradual changes in the types of species that live in an area

The first organisms to appear in an area undergoing succession are known as the pioneer species. These organisms lead to a more biodiverse steady-state ecosystem.

1. true.2. true.3. true.4. false.5. true.the concept of darwin's theory of evolution involves the idea that there are limited resources in a given living environment and that the organisms which live within have variations in their genetic make up due to random mating. the ones with beneficial genetic variations can express certain traits which give them an upper hand in surviving and reproducing in the said environment compared to ones who may have a more disadvantageous variation in traits. over time, the organisms with an upper hand will survive and reproduce more frequently and pass on their beneficial genes while the others die. the result is evolution, where we observe (usually, but not always) eventually, phenotypic distinct changes.
