What do these 8th grade ecosystems worksheets cover?

11 printable 8th grade ecosystems worksheets in 4 skill sets, in the order they appear on this page: populations and invasive species; food webs and matter cycles; symbiosis and predators; and biomes and biodiversity.

What happened when wolves returned to Yellowstone?

In 1995 and 1996, biologists released 31 gray wolves in the park, and the northern elk herd later fell from about 17,000 to fewer than 4,000. The sheet asks students to trace effects through the food web. It also separates measured facts from claims that are still debated.

What is the difference between mutualism, commensalism and parasitism?

In mutualism both partners gain, in commensalism one gains and the other is not affected, and in parasitism one gains and the other is harmed. Root Fungus Partnership Growth Data uses pine seedling heights to decide which one fits. The coral reef fact file adds the partnership between coral and algae.

How do scientists compare plans to protect biodiversity?

They weigh each plan by cost, how many species it helps and what it gives people, such as crops or wood. Three sheets compare forest restoration plans, wildlife crossings and pollinator plans with sample data. Students write a recommendation backed by numbers from the page.

Frequently Asked Questions

An invasive species arrives from somewhere else and often has few predators, so it can spread fast and harm native living things. The emerald ash borer kills ash trees, and Burmese pythons in the Everglades are linked to big drops in mammal sightings. Both sheets ask students to use evidence from the page.
