On Friday, D period class went outside to discuss the world’s biomes. I really liked going outside. It helped me visualize how our area would be different in different biomes. I liked the brochures idea, although as a result from School Loop dying and a power outage, many students did not have them in. That was a pity because I felt like we could have talked about biomes more/stayed outside longer. I noted the similarities and differences the alpine and tundra biomes had. They are both cold, have high winds, and had snow in the winter but less or not at all in the summer. The alpine was all over the globe, while the tundra was mostly in the Arctic Circle region. I really liked how the class was structured on Friday.

How do organisms affect one another’s survival?

Organisms can be separated into two main groups according to what they eat, autotrophs and heterotrophs.  An autotroph is a producer that makes its own food.  Heterotrophs are consumers and can be either carnivores (eat animals) or omnivores (eat both animals  & plants).

On the class trip outside I observed many things that support these facts about the food chain and ecology.  For example birds eating insects.  I also observed fish and their nests around the pond.  In addition, there were many different plants that help animals to survive by providing food for them,  the plants also help filter the water and provide oxygen.

An example of this in nature is that worms and other insects are eaten by birds and other animals to provide nutrients for the animal that eats them.  Also another example of this in nature is that plants provide energy for herbivores and omnivores.

If all of the plants died then so would all of the herbivores and the animals that feed on the  herbivores.  It would eventually lead to an entire disaster because all organisms would starve and die.

If one organism dies it does not have as much of an impact on the ecosystem than if an entire species because there would still bee food/energy to provide for all of the other organisms.

It is difficult to make accurate predictions about changes in communities of organisms.  This is because you never know if the organisms could make adaptations and still survive.  We would never really know until the situation actually happens.
