No, because they are competing for the same resources, so one species will outcompete the other.
But, different species can occupy similar niches.
Three species of warblers and their niches
Species are adapted to survive in certain biomes.
Adaptation: an inherited condition that increases an organism’s ability to survive and reproduce.
Ex: eyes, camouflage, fur, claws
Ex: traveling in herds for protection or hunting; producing a large number or small number of offspring
(roots are extremely important)
Plants: Available sunlight, prevention of water build-up
Animals: predators, competition with other species
Both: human activity (deforestation)
(huge difference in temperature in winter and summer)
in the autumn, and grow new ones in spring)
Why would it be advantageous to do this?
Other Plant Adaptation Examples:
Temperature variation in 1 day
(very hot during the day; very cold at night)
when it’s cooler at night)
this helps them absorb solar heat.
Cool temperature, short growing season
Long, dry Summers (most of rain falls during the winter)
Occasional fires (in summer)
