Making Maps for Your Invasive Species

MAP CHART– go to this site to create your own maps.– is a great site to search for your species and find maps already created.– is a site where you can search for your species and it will tell you where it is located. You can then use this information to great your maps.

Thursday, December 6th: Ecosystem Energy Flow

All of the ECOSYSTEMS (packets for our activity) had the same organisms, so why aren’t all of the food chains exactly the same?

Friday, November 30th: Types of Consumers


DECOMPOSER from–webs-trophic-pyramid.html

Decomposers are Nature’s ‘garbage’ recyclers! They are a special group of organisms that obtain their food by consuming dead or decaying organisms and break them down into smaller molecules called “nutrients.” Some of these nutrients enter the soil and are dissolved in water where they can be taken up by plants through their roots or by fungi through their root-like mycelium. Decomposers can be fungi, bacteria, insects and small animals such as crabs.

  • Decomposers that have mouths are also called detritivores.  Examples include worms, crabs, fly maggots (yuck!)
  • Decomposers that don’t have mouths to eat with, break down or digest dead organisms using special enzymes and then absorb the nutrients (like a sponge absorbs water). Some examples of these decomposers include fungi and bacteria.

Tuesday, November 28th: What Makes a Healthy Ecosystem?

Nature Works-

A healthy ecosystem consists of native plant and animal populations interacting in  balance with each other and non­living things (for example, water and rocks). Healthy ecosystems have an energy source, usually the sun. The sun provides radiant energy for producer (plant) growth. Producers change radiant energy into  chemical energy for use by themselves and by consumers. Consumers eat  producers. Higher­level consumers also eat other consumers. Decomposers break  down dead plants and animals, returning vital nutrients to the soil. Plants take up  these nutrients, along with water, through their roots. Ecosystems have definite  boundaries. Components of a healthy ecosystem include: · sunlight (energy source) · living organisms (producers, consumers, decomposers; predator/prey) · non­living things (land forms, water sources, soil, rocks) · dead organisms · natural boundaries (set by the living and non­living things within the area).
