Question

Which organism is a producer

1-oak tree
2-mushroom
3-mountain lion
4-butterfly

Answer 1

Answer 1, oak tree

Step-by-step explanation:

producer organisms are organisms that are mostly photosynthetic organisms like plants, some bacterias and unicellular organisms like euglena.

So the answer is 1 an oak tree because it is photosynthetic.

To see the others mushroom may be a plant like organism but it is not photosynthetic because it doesn't contain chlorophyll.

Mountain lions are not photosynthetic that means they are heterotrophs( organisms that cann't make their own food).

And butterflies are also heterotrophs
