Explain the concept of order in a system (e.g., first to last manufacturing steps; trophic levels; simple to complex—levels of biological organization from cell to organism).

Activities

Outline the steps that must be taken in order to create a shirt from cotton.
List in order, from simplest to most complex, the components that make up an organism.

In a food chain, how can primary producers be compared to carnivores?

When looking at a diagram of a food chain, if the producers are killed because of pollution, how do you think it would affect the other trophic levels? Explain your reasoning.

Answer Key/Rubric

Acceptable responses may include, but are not limited to:
- The cotton must be harvested.
- It is sent to a factory to be cleaned.
- The factory will create thread from the cotton.
- The thread is then woven into cloth.
- The cloth is cut and sewn to create a shirt.

Acceptable responses may include, but are not limited to:

Acceptable responses may include, but are not limited to:
- Producers use energy from the sun to grow.
- Primary consumers eats the producers.

Acceptable responses may include, but are not limited to:
- The 1^st level carnivorous consumers would have to find another food source. They would have to eat things like cockles.
- There would be a shortage of food for the 1^st level consumers. A lot of them would die.
- This would affect the 2^nd level carnivorous consumers because their food supply would also be decreased.
- The 3^rd level carnivorous consumers and top carnivores would also have a decreased food supply.
