What is a tundra?

# data[].attributes.body
A tundra is a vast, flat, treeless Arctic area where the subsoil is permanently frozen.

The arctic fox uses the caribou to hunt while the caribou remains unaffected. The caribou digs up snow and soil to hunt lichens, so the arctic fox follows. Once the caribou is done, the fox either digs deeper holes to get to its prey or eats the animals unearthed by the caribou.

Fungus and algae work together to form lichen. The algae uses photosynthesis to produce sugars which the fungus also eats and the fungus provides protection for the algae. Both benefit.

Liver tapeworm cysts grow on the bodies of animals such as moose, caribou, wolves, etc. The host animal is weakened from this relationship since the tapeworms feed off of the food they eat.

Climate change is a change in global or regional climate patterns that effect each and every biome in its own way. For the tundra, this leads to loss of homes when things melt or shift and annual warmth for the animals.

In the Climate graph (Climatograph), it shows how and what it is like being in the tundra. First it shows that there is not that much rain that is happening throughout an entire year in the tundra (but there is some!). However the graph also is showing the tempertature of the area. It happens to be from a range of semi warm in the summer months to freezing cold in the winter ones.

In all, the burning of fossil fuels are a major lead towards global warming. Which obviously warms up the world. This gets rid of many habitats in the polar zones (for example the tundra biome). Many animals thrive on the fact they there is ice to live on and without it being cold, that ice could easily break apart or melt. To help and stop this draining cause, you can do simple things like turning of the light when you leave a room or not using the TV for a day. This lowers the amount of fossil fuels needed to be burned to keep up with the uprising demand.

A tundra food web is the basics on who eats what for energy. They do this so they can survive and be able to maintain a healthy life.

More roads and buildings in the area attracts more human traffic. Stepping on a plant is enough to kill it, so the increase of humans in the area is killing them. Plants hold the soil together, and without them, erosion may occur.

Humans are also adding to pollution in the air. Air pollution, in addition to hurting the ozone layer, has particles that can be absorbed by plants, which in turn contaminates the food sources for plants.

Oil drilling that humans do can release harmful gases and materials that can contaminate the area. Water, land, and air in and around tundras are therefore polluted by this human activity.
