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

List:
frog, human, hawk, flies, grass, snake, bacteria, mice, grasshopper, flea, rotton fruit, fish

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

I like to use the metal bottles with the twisty tops because it uses less plastic and is better for the environment. It also holds more water and keeps me hydrated for longer times that way.

I use them just for water and the one I am currently using has been refilled a few times.
Is it bad to keep refilling them?
Does bacteria build-up?
Or is it safe to just keep reusing it?

Thanks in advance(:
