What is the original source of energy for an ecosystem? Describe how that energy is transferred to different organisms in that ecosystem.

List:

a)name all the producers in the list
b)name all the hervivores in the list
c)name the carnivores in the list
d)name the parasite in the list
e)name the decomposer in the list

Using those words in the list how could i draw a food web using eight of the organisms

Whats the difference btw. food web and food chain

question#1- in a food web,if the number of food chain connections is decreasing,you ‘ll find more
1-species
2-herbivores
3-unrelated spescies
4-carnivores.

question # 2-
which of the following will cause a predator-prey relation to be thrown off balance?
1-food levels remain steady.
2-faster reproducton in prey than in predators.
3- equal reproductiov rates in both species.
4-a third neutral species is introducted into the environment.
please give sure answer.
thanks in advance.

I’m working on a project for Biology and my topic for a poster is Ecology-> interconnectedness-> food web not food chain and modle simplification

The question says it all. Do you think there would be change anywhere (environment, ecosystem, food chain etc.)?
This question was on my mind since I first heard of global warming and climate change. It seems to me that humans do nothing but ruin the environment. I would like to see if anyone agrees or disagrees with me. Please think carefully before answering. Everyone is welcome to express their opinions.
Thank You.
