Step-by-step explanation:
Answer:
Volume of emerald = 137.04cm³
Step-by-step explanation:
Given that:
Mass of emerald = 378.24grams
Density of emerald = 2.76grams/cm³
Volume = ?
The equation for this relationship is ρ = m / V in which ρ is density, m is mass (kg or g) and V is volume (cm³ or m³) making the density unit kg/m³ or g/cm³.
Therefore
Density = mass/volume
Volume = Mass/density
i.e
Volume of emerald = Mass of emerald / Density of emerald
Volume of emerald = 378.24grams / 2.76grams/cm³
Volume of emerald = 137.043cm³ ~137.04cm³
Volume of emerald =137.04cm³
Answer;
-The populations of grasshoppers, mice, and snakes would decrease.
Explanation;
-The food web or a food chain describes the series of relationships that occur between predators and prey in an ecosystem.
-Several types of life forms form the food web. Green plants that can make their own food through photosynthesis are the web's producers. They form the bottom of the chain. Animals that get food from other animals and plants are consumers. Decomposers feed off dead plants and animals because decomposers cannot make their own food.
-If producers were removed in a food chain then, all the other animals in the food web would die too, because their food supplies would have died out. The populations of the consumers would fall as the population of the producer fell.
