1. Adaptations made for Survival

Nocturnal Activity- alien needs to be able to be active more in the night time to avoid daytime temperatures and to stay cool.

Burrowing- the alien would need to be able to do this to retain water by burrowing it into moist soil. This allows the animal to obtain water that is needed for its survival.

Change in color-the alien would need to be able to blend in with the sand or it would become quick food source for the bigger animals.

Hibernation- it would also adapt to hibernate to survive extreme climatic helping them reduce their body temperature. This also allows them to slower their metabolic rate.

2. How it obtains energy

The alien obtains it's energy by eating plants found in the dessert and rats because the alien is not able to produce its own.

4. Habitat

The alien would live underground where the temperature is much lower and not as hot. it makes this habitat by using its fingers and claws to dig holes in the ground big enough to for it fit through the whole. Physically the aliens have adapted to be smaller in order to fit in their habitat, and behaviorally the alien has adapted to become more active at night rather than be out during the day.

5-7 Realtionships:

Mutualism- because of the extreme climate in the desert many organisms do not like to be out during the day and so most of the animals tend to have the same habitats. The snake also has the same habitat as the alien and so whenever the snake makes it hole the alien can also fit in the same hole to use as a habitat and not having to dig a hole. And same for the snake whenever the alien creates a hole the snake can also use that same hole for protection from the sun.

8. Competiton

The alien would have competition for food with the snake because they eat the same thing for example the rat and they don't eat that many other organisms. If this were to continue then the alien would have to find another organism to eat or only eat plants.
