Two parents both have brown eyes (dominant trait), but their child has blue eyes (recessive trait).
What is both parents are heterozygous (carry the recessive allele), so the child inherited two recessive alleles?
This limits the growth of populations due to limited resources.
What is competition?

Coal, natural gas, and fossil fuels.
What are nonrenewable resources?
How does unequal heating of Earth drive weather patterns?
Creates convection currents in atmosphere
From producers → consumers → decomposers
