The Desert

by: Nathan Patterson

Ecology is a specific branch in biology, that deals with organisms responding to one another, and to their surroundings.


The roadrunner is one of many animals that populate the desert. Population is a particular group of animals living in a specific area. Roadrunners live mostly individual- separate- or in pairs, this is why I could not find a picture with more than one in it. Roadrunners live usually in nests a few feet above the ground in a bush, tree, or cactus. When the nest is being built, both male and female will help build it. Some of these birds have been able to run up to 20 mph!


The owls in the picture above, living on the cactus, is commensalism. This is where one organism benefits, but the other does not. The other however, is not harmed. These owls are also an example of a community. A community is a group of living people, or animals, living together. If the owls were to get water, from the cactus, this would be an example of an ecosystem. The owls are getting water, which is an abiotic factor.

Six Kingdom Classification

The first picture above is the Trichonympha agilis, of the protista kingdom. The second is a Cactus, which is part of the plantae kingdom. The third picture, the Battarrea phalloides, is part of the fungi kingdom. The last picture is a Hyena pup, which is part of the animalia kingdom. The protista kingdom is any of the various one-celled organisms, they also reproduce asexually, and can be heterotrophs or autotrophs. The plantae kingdom have cell walls, they are eukariyotic, and can reproduce sexually or asexually. The fungi kingdom can be either multi or single-celled, reproduce asexually, and have cell walls. The animalia kingdom are multi-cellular, have circular cells, and reproduce asexually and sexually.

Food Chain

The plants in the food web are producers. A producer is an organism that makes it own food, so most of these are plants. Another word for producer is autotroph, which is what most plants are.

The fox in the food web is a consumer. A consumer is a organism that consumes, or eats, other organisms. Heterotroph means the same as consumer. It does not make its own food.

The Battarrea phalloides, which is not on the food web, is a fungi. It is also a decomposer. A decomposer is an organisms that brakes down its prey. Fungi are heterotrophs.

A single food chain would be a straight line of organisms being consumed, with no other consumers; such as; lizard to snake, then to the fox.

Abiotic Factors

The first abiotic factor is sand, which is obviously all over the desert. The second picture is rock, which are also nonliving. The last picture is water, which for some animals is used as a home, and is an essential for living.

Lots of organisms depend on these abiotic factors for homes. These 3 factors may be essential to some organisms survival.
