RELATIONSHIPS IN ECOSYSTEMS: COMPETITION


Sometimes living things compete with each other to get what they need because they need the same things.
We call this competition.

  • Plants compete for sunlight. Some plants grow very tall, very rapidly. Plants in the shade of other plants do not grow very much.
  • Some birds compete for places to build their nests. Crows and falcons like the same rocky áreas to nest. Usually the falcons drive away the crows.
