Answer:
The five types of interactions between species are
1) Competition: In such a type of interaction, organisms interact by competing for resources such as water, food resources, shelter etc.
2) Predation: In such a type of interaction, organisms of a species known as predators feed on organisms of the other species known as prey. For example, a lion feeding on a deer.
3) Commensalism: In such a type of interaction, an organism of a species benefits from the other organisms and the other organisms neither gains benefit nor loss. For example, Tree frogs using plants for protecting themselves from predators.
4) Mutualism: In this type of interaction, both the organisms of different species gain benefit from each other. For example, insects carry pollen when they move from one plant to another and in turn they use plant as a source of food.
5) Parasitism: It is a type of interaction in which one organism benefits whereas the other one is harmed. For example, Malaria is caused by anopheles mosquito feeding on the blood of humans.
Mesoderm becomes: The mesoderm forms skeletal muscle, bone, connective tissue, the heart, and the urogenital system. Due to the evolution of the mesoderm, triploblastic animals develop visceral organs such as stomachs and intestines, rather than retaining the open digestive cavity characteristic of diploblastic animals.
Endoderm becomes: The endoderm produced during gastrulation will form the lining of the digestive tract, as well as that of the lungs and thyroid.
Ectoderm becomes: After gastrulation, the embryo goes through a process called neurulation, which starts the development of nervous system. During neurulation, ectoderm differentiates into two parts. The first is the surface ectoderm, which gives rise to tissues on the outer surface of the body like epidermis, hair, and nails.
