Grass and migrating animals have a mutualistic symbiotic relationship. The animals graze on the grass, which helps control the grass height and density, promoting new growth. In return, the animals receive a food source while also dispersing seeds through their droppings, aiding in the grass's reproduction.
Joseph Black discovered carbon dioxide (CO2).
A phylogenetic tree is typically used to show the evolutionary relationships between animal phyla. It is a branching diagram that resembles a tree and represents the evolutionary history and genetic relationships between different taxa or groups of organisms.
The relationship is called parasitism. The cowbirds raid the other bird's nest and lay their eggs there. The other bird has to migrate to another tree to build a new nest.

The spider you are describing could be a black widow spider. Black widows are known for their sleek black bodies and long, thin legs that give them a distinct appearance. They also have a red or orange hourglass-shaped marking on their abdomen.

You are probably defining a false black widow.
Symbiotic relationships are usually referred to as "give and take" but this is not always the case, whilst some may be beneficial eg. mutalistic, commensalistic others are not eg. parasitism. The isopod falls into the parasitic category where one species benefits and the other does not.
Plants make and propagate with seeds. It isn't a symbiotic relationship since that is inter-species. Many plants have symbiotic relationships with insects (bees and flowers). link on symbiosis: http://www.answers.com/topic/symbiosis?cat=health
Only black widows have hourglasses on their backs... You should probably be careful
Mycorrhizae are symbiotic relationships between the roots of plants and fungi that act as extensions of the root system. The fungi supply the plant with certain nutrients, and the plant in turn supplies the fungi with carbohydrates.
Symbiotic.
