Answer: The correct answer would be copper, nickel, or zinc.
Explanation:
Heavy metals such as copper, zinc, nickel have antimicrobial properties due to which they are used in various places to prevent microbial growth. For example, copper sulfate is used in fish tanks and swimming pools to prevent algal growth. Metallic copper and/or copper linings in incubators also help in reducing microbial contamination.
Coating of nickel or zinc is also used for the same purpose.
Thus, the correct answer would be copper, nickel, or zinc.
They are the “food” requires for plants to undergo photosynthesis which creates glucose (an essential nutrient for all life). And since plants are at the bottom of the food chain, “what they eat” can be commonly found at the bottom too.

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.
