Ecology Scavenger Hunt

By Maggie Lazaroski and Paloma Diaz, Period 1

Biotic

Julianna and Elena are both human beings, which means they are living. Living things are biotic factors of an environment.

Abiotic

Water is a nonliving factor, so it is abiotic.

Autotroph

This plant is capable of photosynthesis, so it is an autotroph.

Heterotroph

The people at this cafeteria table are heterotrophs because they cannot make their own food. You can actually see them consuming food (not made by them) in the picture.

Carbon Cycle

The first picture is four ways that carbon can be released into the atmosphere. It can be released by breathing out, volcanoes, emissions from cars and trucks, and power plants. The second picture is one way that carbon dioxide can leave the atmosphere, which is through photosynthesis.

Water Cycle

Maggie represents oversaturated clouds, and the water bottle represents rain. Paloma is pretending to be a lake, as she catches the rain that Maggie pours on her. Then, the water will evaporate out of the lake restoring Maggie's water reserves, which will start the cycle over again.

Nitrogen Cycle

The nitrogen cycle takes place mostly in air, dirt, and plants. The nitrogen from the atmosphere enters the dirt where bacteria fix it for the use of plants, who then return it to the atmosphere.

Phosphorus Cycle

Part of the phosphorus cycle is when humans return phosphorus to the ground when we decay, so here's a picture of dead Maggie.

Current Weather

The weather outside was rainy and hailing.

Commensalism

In this picture, Julianna is holding the door open for Maggie. Holding the door isn't good or bad for Julianna, so she is relatively unaffected. Maggie, however, doesn't have to open the door for herself, so she is saving energy.

Parisitism

Paloma is carrying Maggie, which makes her tired. It also causes her to need more energy from food and sleep. Maggie is getting a free ride from Paloma so that she doesn't have to expend any energy, but at the cost of Paloma.

Mutualism

Maggie and Paloma are hugging each other, evoking positive emotions from both parties. Since both of them benefit, it is mutualism.
