Ecology Scavenger Hunt

Pragat Muthu, pranav anbarasu, and Andrew hatanpaa


We had to find examples of 13 things. They are:

  1. Biotic
  2. Abiotic
  3. Autotroph
  4. Heterotroph
  5. Food Chain (minimum of 4 organisms – label what they are (producer, primary consumer, etc.))
  6. Current Weather
  7. Carbon Cycle (show 4 ways to get carbon into our atmosphere and one way carbon is taken out)
  8. Water Cycle
  9. Nitrogen Cycle
  10. Phosphorus Cycle
  11. Mutualism (type of symbiotic relationship)
  12. Commensalism (type of symbiotic relationship)
  13. Parasitism (type of symbiotic relationship)

Biotic factor

Big image
This is an example of a biotic factor in an ecosystem. The Tree is one of the organisms living in this area. This tree is one of the living parts of this ecosystem.

Abiotic Factor

Big image
This is an abiotic feature of an ecosystem. The reason why is that it is a nonliving portion of this ecosystem. It is a manmade structure.


Big image
This is an example of an autotroph. This is a plant. This plant makes food for itself instead of living off of other organisms.


Big image
This is an example of an heterotroph. This is a cat. This cat eat food made by others instead of living off of itself.

Food chain

Big image

Andrew- Primary producer, Pragat- primary consumer, Gautam- secondary consumer, John- tertiary consumer

The people are organized into a way where each person is eating the other.


Big image
The current weather at the time that the picture was taken was cloudy and rainy.

Carbon Cycle

Water cycle

Big image
This demonstrates the water cycle because water condensation occurred in the clouds, then the water was precipitated, and then it began to evaporate and start the cycle over again.

Nitrogen cycle

Big image
The fish and the seaweed give off ammonia, a form of nitrogen. This is broken down into nitrites, then into nitrates. This nitrates go back into the plants. The cycle starts over.

Phosphorus Cycle

Big image
This is an example of the phosphorus cycle. The rocks release phosphorus into the soil. The plants draw the nutrients(phosphorus) from the soil.Phosphorus enters the biosphere almost entirely from the soil through absorption by plant roots.


Big image
This is an example of mutualism. Both the boy and the girl are happy and benefiting from each other. This is not at the expense of either one of them.


Big image
This demonstrates commensalism, because the students are benefiting by receiving knowledge, and the teacher is being neither harmed nor benefited.


Big image
This is an example of parasitism. As the girl is benefiting from the guy by taking the lunch. She is benefiting at his expense, so he is being hurt.
