What will most likely occur if two different plant species compete for the same requirements in an ecosystem?
They will usually develop different requirements.
One species may adapt to a different requirement.
One species may eliminated from that ecosystem
They will alter the environment so that they can both survive in that ecosystem

Match the organisms with their symbiotic relationships.
Mutualism
Feeds on blood, harming the host.
Parasitism
Tree provides support, moss gains sunlight.
Commensalism
Anemone provides protection, fish provides nutrients.
Match each ecological interaction with a corresponding example.
Plants competing for sunlight
Commensalism
Wolves hunting deer
Competition
Birds nesting in trees
Predation
Question 12

What would happen if all producers disappeared?
Only primary consumers would be affected
The ecosystem would collapse due to no energy input
Decomposers would take over the role of producers
Nothing would change
