Ecological Scavenger Hunt

By: Lauren MacDonald, Iris Loya, and Cristina Gonzalez

Biotic

Biotic means a living organism. Cristina and Iris are living organisms.

Abiotic

Abiotic means the organism is non living. These rocks are non living.

Autotroph

An autotroph means that the organism makes its own food. This tree makes its own food.

Heterotroph

An heterotroph is an organism that cannot make its own food. Iris cannot produce her own food.

Current Weather

The current weather in Coppell Texas on Tuesday was rainy and cloudy.

Carbon Cycle

In this cycle, carbon from the atmosphere goes into organisms and back out again. An example is humans. When we breathe, we breathe out carbon dioxide.

Water Cycle

The process in which water circulates from land to the sky. In this picture it shows how water is on the ground. It will eventually evaporate and go to the sky and begin the cycle.

Nitrogen Cycle

The nitrogen cycle is the circulation of nitrogen in nature. Bacteria releases nitrogen, plants absorb it, plants die and decay, then nitrogen goes back into the air.

Phosphorous Cycle

The phosphorous cycle is the movement of phosphorus through ecosystems. The cycle starts from sediment then moves to living organisms.

Mutualism

This relationship is when both organisms are benefited. The flower is getting pollenated and the bee is getting food.

Commensalism

This relationship is when only one of the organisms benefits. For example cars and humans, we benefit by getting to drive the car but the car doesn't benefit from us driving it.

Parasitism

This relationship is when on of the organisms involved benefits from it but the other on is being harmed. When a dog has ticks, the ticks are benefiting by getting a food source but the dog is being harmed.

Food Chain

A food chain is a chain of what organisms eat to stay alive. With the different grades it shows the different populations or the different grades of the food chain/ school.
