Barnacles often attach themselves to whales and receive free transportation to parts of the ocean. The whales are not affected by this activity. This is an example of

(1.) mutualism
(2.) saprophytism
(3.) commensalism
(4.) parasitism

Several years after a building had been torn down and the ground cleared, grasses began to grow in that area. After 10 years, small bushes replaced the grasses. This pattern of plant growth is known as

(1.) cover cropping
(2.) land use management
(3.) ecological succession
(4.) biological control
