What does threats to their survival mean?
These are factors, human or otherwise, which affect survival of a species.
How can non-native species affect the survival of native species?
they have effect on it by eating and killing all the native species
What factors affect the survival and change of a species over time?
Adaptation is the main factor in ensuring a species survival. Part of that adaptation may mean evolutionary changes, as newer, more adaptable members of a species become dominate.

One species beneifits the other spices is harmed?
This is an example of an ecological concept known as interdependence. It occurs when the actions or presence of one species positively affect another, while negatively impacting a different species. This can lead to complex relationships within ecosystems where different species rely on each other for survival.
How does variability within a species affect its survival?
The introduction of a new predator, the spread of a new disease, the introduction of a toxic substance, or the elimination of a food source are all examples of environmental changes that could affect the survival of a species.
How can a limited resource affect the survival of a species?
When 2 species directly compete for a limited resource, only 1 will ultimately be sustained in that space. The other will die out
Does natural selection affect the survival of an individual or a species?
Natural selection affects the survival of individuals within a species. Individuals with advantageous traits that better suit their environment are more likely to survive and reproduce, passing those traits onto the next generation. Over time, this can lead to changes in the species as a whole.
How changes in environmental conditions can affect the survival a species?
If a species lives in only one particular salt marsh biome and the sea level rises to inundate that biome. all members of the species will die out.

How might their destruction affect the long term survival of species?
As habitats disappear, the species that live in those habitats vanish. In addition, development often splits ecosystems into pieces.
How do humans affect the survival of penguins?
One way in which humans affect the survival of penguins is by altering its habitat. Pollution of oceans is one way humans affect the penguins' survival. Another way is by over-fishing the oceans. Penguins are seabirds and eat fish. Global warming is melting the ice that Antarctic penguins need to roost and breed. In more temperate areas, such as Australia's southern shores where Little Penguins live, introduced species such as dogs and feral cats affect the penguins' nesting sites, killing these small and defenceless birds on land.
