No. A 'renewable resource' is a resource replaced by natural processes at a rate comparable or faster than its rate of consumption. Since chocolate is not replaced by a natural process it cannot be a renewable resource. Answer Yes. Chocolate comes from cocoa plants and plants are generally considered to be a renewable resource. We could plant enough cocoa trees to replace what is harvested. Thereby ensuring we have a constantly renewable source of chocolate.Rebuttal to second answer:Except that chocolate is a MANUFACTURED product, therefore CANNOT be a renewable resource. Ok. The above answerer is using a very narrow definiton of "renewable". It can also apply to commodities. For example: ethanol from sugar cane is a manufactured product. Ethanol fuel that can be used to run cars is considered to be a renewable energy source if it is grown sustainably. So we can consider that plant products such as chocolate are renewable if managed correctly.
using solar energy instead of natural gas to heat water
No Renewable energy is energy that is replaceable at a reasonable rate for example coal is replaceable but it takes to long to replace it. wind is because it is so replaceable that we dont need to replace it. Solar energy is for the same reason as wind. In most cases Natural resources are the equivalent of renewable resources but not always.
If it can be replaced at the same or higher rate that it is being used up, it can be sustained. If I use 100 trees a year,but grow 200 new trees each year, that can be sustained. If I use 100, but plant only 50, eventually I run out of trees.
Food is classed as renewable, because we can grow more after we've consumed the first lot.
The resource will run out.
It is called nonrenewable :)
Natural resources, such as coal or oil. These are formed over immense periods of time. Other resources, such as wood, can be grown again relativly quickly, so consumption can be moderated to the new growth rate ensuring a sustainable resource.
Silver is classified as a nonrenewable natural resource. It is extracted from the earth's crust through mining processes, and its supply is limited. While new silver deposits may be discovered, the rate at which they can be replenished is much slower than the rate at which silver is consumed.
A non-renewable resource is a natural resource which cannot be produced, grown, generated, or used on a scale which can sustain its consumption rate. These resources often exist in a fixed amount, or are consumed much faster than nature can create them

it's renewable, because it is produced at a faster or same rate as it is consumed!
A resource that can't be used again! Nonrenewable resources are resources which take thousands of years to form, like coal, oil, natural gas, uranium etc. Any natural resource that cannot be remade or reproduced once it is used up is 'non-renewable'. It means that something can't be used again.

using solar energy instead of natural gas to heat water
Oil and natural gas are considered nonrenewable resources because they were formed over millions of years from the remains of ancient plants and animals. The rate at which they are extracted and consumed is much faster than the rate at which they are naturally replenished, making them finite resources. Once these reserves are depleted, they cannot be easily replaced within a human timescale.
