Describe the features of a species with type 1 survivorship that aid in high juvenile survival:

Aldo Leopold
Philosopher who said the protection of the interacting parts in an ecosystem ensures its health. "To keep every cog and wheel is the first precaution of intelligent tinkering."
Green Taxes
Taxes on environmental harmful acts.
Discuss the following statement: "There is no standard survivorship curve for a given species; the curve depicts the nature of a population at a particular time and place and under certain environmental conditions."
The statement is true. A standard survivorship curve just merely represent the population and mortality rate in its natural environment and at a certain time. If we moved the organism to a place with more or less predators the mortality rate would be affected. But this applies more to type 2 and 3 rather than type 1. Type 1 has the ability of surviving for longer period of time even if the environment changes due to their ability to adapt. But in general there is not survivorship curve.
