32. What is competition?

33. Define the word competition as it might be related to the field of ecology.

34. Competition: The interaction between organisms or species, in which the fitness of one is lowered by the presence of another. Competition: The interaction between organisms or species, in which the fitness of one is lowered by the presence of another.

35. Four types of competition

36. Interspecific competition: Over resources between different species.

37. Intraspecific competition: The same species compete for resources.

38. Interference competition: fighting / disrupting.

106. Disguise: This is like concealing coloration except that the animals blend in with their surroundings by their shape and/or texture rather than color.
