  • Write our hypothesis: Establish a hypothetical result that we are going to demonstrate.
  • Gather the materials: We must have all the materials and variables to be able to carry out our experiments.
  • Analyze the data: When we do an experiment we must record everything we see and then analyze it to examine each step and the procedures performed.

Please help meeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeee
Mrrafil [7]

Answer:

number 1 answer is 3.

number 2 energy is flowing upwards. ex grasshopper eats the grass, rat or whatever that is eats the grasshopper, and the hawk eats the rat. energy is going up each trophic level.

number 3. if the grass became polluted, then animals would get pollution in their bodies and at some point would die. eventually the grass would die too. primary consumers such as mouse, rabbit, grasshopper/snails would accumulate the most pollution because they directly eat the grass. whatever that is in the grass goes straight into their bodies.
