Nature's Life Cycle
Overview:
In this podcast from The Friends of Auntie Litter", the Patrol learns that one very important characteristic of all living things--plants and animals--is they carry on respiration.  They also move, reproduce, grow, and take nourishment.  Bobby Bunkle describes a food chain as he scuba dives.  Since plants and animals are so important, it's crucial to protect the environment in which they live.  The Grunge, for instance, doesn't understand that trees provide animals with oxygen and homes, so he likes to cut them down.

Planet H2O- Water Pollution and the Aquatic Food Chain
Overview:
Biomagnification is the accumulation of a substance up the food chain by transfer of the pollutant in smaller organisms that are food for larger organisms in the chain. It generally refers to the sequence of processes which results in higher concentrations in organisms at higher levels in the food chain (at higher trophic levels). These processes result in an organism having higher concentrations of a substance than is present in the organism’s food. There is evidence that some carnivores at the ends of longer food chains (e.g. larger fish, birds of prey, HUMANS) can then accumulate the water pollutant from eating down in the food chain. Clean fresh water is vital to life on our planet. What can happen if our waters become polluted? How can that affect us as humans if it is happening in the water and to the organisms in that water? One of the ways pollution impacts humans is through food chains. We have to remember that we are part of the environment and as a result, part of the food chain. We eat many of the aquatic organisms, fish and shellfish, which can be detrimentally affected by water pollution.
