Final answer:
In biology, an organism has to allocate its energy between growth and reproduction. Each millimeter of growth costs 11 J, and each egg produced costs 3 J.
Step-by-step explanation:
In biology, an organism has a limited amount of energy that it needs to allocate between growth and reproduction. Each day, the organism has 900 J of energy to divide between these two processes. However, each millimeter of growth costs 11 J and each egg produced costs 3 J.
To calculate how much energy is available for growth and reproduction, we can use the given information. Let's say the organism allocates 'x' millimeters for growth and 'y' eggs for reproduction. The equation we can use is 11x + 3y = 900. This equation represents the energy expended on growth and reproduction.
By solving this equation, we can find the values of 'x' and 'y' that satisfy the equation. These values will tell us the amount of energy allocated for growth and reproduction.
