Most ecosystems use the ____________ as their energy source.
Animal populations usually include

What are the four relationships in ecosytems?
The competition relationship is when the members of the same population have to compete for a limited supply of food. This competition prevents
the population from getting too small.
from getting sick.
the population from growing too big.
from spending too much money on candy.
The Predation relationship is when predators hunt other animals for foods. This relationship allows
for the predators to have no have enough food to eat.
their prey to grow in large numbers.
their prey to keep from getting sick.
plants to thrive and grow, by keeping too many herbivores alive to eat them.
The relationship parasitism causes disease, and slows how quickly or a large a population can grow.
What is the relationship Mutualism?
they all get a long and sing and dance.
it helps both groups of animals or living things (partners).
it only benefits one group of animals or living things (partners).
it benefits neither group or living things (partners).
True of False: plants absorb the sun's energy, then passes it on to the organism that eats them. This is called photosynthesis.
A coniferous forest has
cone bearing fir trees.
small needle trees, near the ocean.
cone bearing needle trees, lakes, and rivers.
trees with large fan like leaves, lakes and rivers.
