Answer:
A virus attaches to a specific receptor site on the host cell membrane through attachment proteins in the capsid or via glycoproteins embedded in the viral envelope. The specificity of this interaction determines the host (and the cells within the host) that can be infected by a particular virus.
Explanation:
Herbivores
Carnivores, organisms that consume animals, and omnivores, organisms that consume both plants and animals, are the third trophic level. Autotrophs are called producers, because they produce their own food. Herbivores, carnivores, and omnivores are consumers. Herbivores are primary consumers

Rain forest contains more species
Yes, they do. Many plants will have seed pods (like dandelions) that fly away or drop off. This helps distribute the seeds and promotes more plants being grown elsewhere. Another adaptation would be having their seeds inside fruits. This causes other animals to eat it and distribute the seeds that way in their waste.
