Question

Question 10 play In the phylogenetic tree shown, which is true about the characteristic "gestation"? Otisa shared derived character for the clade including the beaver and kangaroo O it is a shared derived character for the clade including the beaver, Kangaroo and platypus o it is a shared ancestral character for the clade including the beaver and frog Otisa shared ancestral character for the clade including the beaver and kangaroo Question 11 The level of biological organization that addresses how organisms interact with abiotic factors is the community O population O species O ecosystem

Answer 1

10.The phylogenetic tree shows the ancestral relationship of animals . In phylogenetic tree common shared character are represented by nodes. Here in the phylogenetic tree there rre only two animals that show gestation, viz, kangaroo and beaver. And they show a common ancestor too. So we can conclude that gestation is the shared derived character for the clade including kangaroo and beaver.

11. Ecosystem consist of all the biotic and abiotic factors that interact each other . Species represent the group of related organisms which can reproduce sexually. Population is the group of organisms of same species living in smae area. Community is the group of organisms of different species which live in the smae area. Community, population, species do not adress any abiotic factors. But ecosystem addresses both biotic and abiotic factors and their mutual interaction .
