Astronomers have seen stars forming within a nebular cloud. As the nebular cloud condenses and its own gravitational attraction collapses it, heat and energy build up creating a planet.
Invasive species reduce biodiversity levels, create a nuisance, cause economic loss, and disrupt ecosystem equilibrium.
<h3>Effects of invasive species</h3>
- Invasive species tend to drive away or kill native species.
- Invasive species reduce the overall biodiversity of plants or animals in the ecosystem.
- They cause economic loss through the loss of important native species.
- They create nuisance in the environment and may be costly to get rid of.
- They affect ecosystem equilibrium by causing species change.
- They are usually difficult to manage.
