What dies survivor ship curve mean? What an easy way to remember what it means?
vredina [299]
Survivorship curve = so, first of all, it's a curve, as in a graph.

It describes "survivorship" - the rate of survival, in other words: out of 100 organisms that are born, how many survive. This rate is different among species, for example, most humans live out to most of their life span, and almost all can survive well beyond a reproductive age.

However, in frogs for example, many many individuals are born, but only few can survive to adulthood: most die very young, before reproductive age.

So if you hear about a new species: let's say dogs, and you want to know how long they would live, you would look at their sirvivorship curve (and in some breeds of dogs, those that are likely not to be in shelters, but in homes, the survivorship curve would be similar as in humans: almost all individuals born can live long.

What structure is required for an eukaryotic organism to be classified as an autotroph?
lara [203]

Answer:

Chloroplast

Explanation:

This organelle in cells indicates that an organism can harness energy from the sun and other abiotic factors like carbon dioxide to make their own ‘food’. Chroloplasts have chlorophyl piments that contains photosystems centers that harness energy from the sun for photosynthesis. This light energy from the sun is captured and transferred in chemical bonds of manufactured carbohydrates which are stored in the plants. These plants transfer this energy in an ecosystem when they are consumed by higher organisms in the food chain.
