Nancy visits a local reservoir where she feeds ducks and other birds. Every time shefeeds them she notices that they fight for the best pieces and some do not get any. Allliving things struggle to get the necessary amount of food, water, and shelter. What is theterm for this struggle?

if the type of the food available changes, then the frequency of beak types will change, because birds with beaks more suited to the available food will be more successful over time.

looks like the answer is     c     to me!

garbage disposal because lysosomes dispose of old cell parts like garbage disposals dispose of old food.
