Commensalism
yes.
parasitism
No. Because grasshoppers live a different way then a deer.
Deer and burdock have a complex interaction where deer often feed on burdock plants, particularly young leaves and shoots. This browsing can affect burdock's growth and reproduction, potentially limiting its spread in certain areas. However, burdock's robust nature allows it to regenerate and thrive in various conditions, so while deer may reduce its populations locally, burdock can still persist and adapt in the environment. Additionally, burdock's seeds are often dispersed by animals, contributing to its propagation despite herbivory.
The relationship of a tick to a deer is parasitic, not symbiotic.
The symbiotic relationship between a moose and a deer would likely be commensalism. The deer may benefit from being in the same habitat as the moose without significantly affecting the moose either way.
the symbiotic realtionship between deer and birds is mutalism and sometimes neturalism
The cougar is in symbiosis with the deer. The cougar hunts and keeps the deer population in balance by preying upon the weaker animals, and the deer provide the cougar with a food source.
parasitasm
Yes, there can be a symbiotic relationship between a tree and a bird building its nest. The tree can provide shelter and support for the nest, while the bird can help disperse seeds and fertilize the tree through its droppings. This relationship benefits both the tree and the bird.
Producer (grass) and First Level Consumer(deer).
The plant is a producer and the deer is a consumer.
