Interactions Within An Ecosystem | Ecology and Environment | Biology | FuseSchool
Ecosystems are large, often highly complex areas of our environment.
In this video we learn how abiotic and biotic factors interact with one another in a ecosystem, how trophic levels work, and how various factors in an ecosystem lead to evolution of species through different selection pressures.
Our teachers and animators come together to make fun & easy-to-understand videos in Chemistry, Biology, Physics, Maths & ICT.

Let’s discover some more circle theorems so that we can solve all types of geometrical puzzles.
We discovered these 4 theorems in part 1:
Angle at the centre is double the angle at the circumference
The angle in a semi-circle is 90 degrees
Angles in the same segment are equal / Angles subtended by

If we don't have the vertical height of a triangle, then we can find the area of the triangle using 1/2absinC.
In this video we are going to discover where this formula comes from. The formula is based on area = 1/2 base X height and a
