Pyramid of energy (each letter is a different "box"….increasing in size<>a to d) energy is pointing in both directions<—->
a
b
c
d
<———-energy———>

1. the box representing producers is labeled(a,b,c or d)?
2.large carnivores are represented by the box labeled(a,b,c or d)?
3.energy is dreansferred from(a,b,c or d)? to (a,b,c or d)? in this diagram.

True or false(if false change a word to make it true) the word to change is marked with a **next to it.
1. all producers are *heterotrophs.
2. *consumers are organims that eat only producers.
3. fungi are *autotrophs
4. *carnivores eat other heterotrophs.
5.*omnivores eat both autotrophs and heterotrophs.

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

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.
