An ecosystem is a system of organisms that interact with each other and with the non-living parts of their environment. Energy flows through food webs & Matter cycles within food webs.
More Notes:
Food web, producers, consumers, primary consumers (herbivores), secondary consumers (carnivores). Secondary consumers eat primary consumers. Top consumers don't get eaten!
Some animals are...
Herbivores: Cows, sheep, deer, rabbit, grasshopper
Omnivores: Spider, pig, bear, racoon, chipmunk, human
Carnivores: Lion, wolf, snake, hawk, praying mantis
Are ALL consumers.

Reflection Questions:
| Answers:2. I think it could be considered a system because, it is almost always going to stay the same. No bunny is going to eat a wolf! It is a big system of nature. 3. All the animals an plants would be effected, and eventually maybe die out. Because if the lions die out, there will be way to many gazelle, and then all of the gazelles food would run out, then eventually the gazelle would die out. 4. When a living organism eats something, they get nutrients from it and store some of those nutrients away. And when another animal (predator) comes and eats that animal, they get the nutrients that it had stored away. 5. They get body warmth and motion from energy. This energy comes from it's food. What I said in answer 4 is how animals get energy. 6. I think the matter is stored away for later, as body fat. If the animal was in desperate need of food they could get stuff from that stored energy/fat. |
