Answer:
Producers are the source of energy in a food chain.
Explanation:
Producers, through the process of photosynthesis, make their own food. When a primary consumer eats the producer, they get the energy stored by the producer. When a secondary consumer eats the primary consumer, the energy is transferred again.
The first historical record associates the beginning of sugar in the Americas with Christopher Columbus' initial and epic voyage of the discovery of the New World in 1492.
The sugar cane plant is native to Southeast Asia and in Europe had already created an appetite for more through the Eastern trade routes. These were of course difficult routes that included trade caravans over land and water to reach Asia from Europe.
With Columbus the initial planting of sugar cane occurred in the Dominican Republic. The Caribbean islands maintain a perfect tropical climate for the plant and as such, flourished. Other colonizers, like the British, Portuguese and French soon followed suit within their own colonies spread throughout the New World.
The Portuguese had transplanted or moved some of the seedlings, or small plants from the Dominican into Brazil and other areas of their colonized lands. In fact, Brazil is the largest producer of sugar cane in the world today.
The desire for more sugar during this early settlement, led to a "triangle of trade". In order to satisfy the need for production of sugar, ships sailed to the western coasts of Africa to bring slaves to work the sugar plantations. After depositing the slaves, the ships would pick up sugar and rum, an alcohol created from sugar, and bring these goods back to the European powers. This completed the cycle for the ships, which would then return to Africa to gather more slaves.
By 1505, this trade route was set up and going strong. And for the next 300 years or so, would remain in effect.

The naturally occurring solid mixture of one or more minerals and organic matter is known as a Rock.
A rock is a naturally occurring substances that is a solid mixture of one or more minerals together with organic matter.
<h2>Further Explanation;</h2>
- Rocks are classified based on the chemical composition, texture and the way they are formed. One type of rock may change from one form to another through a rock cycle.
- Rock cycle is the process through each various rocks change from one form to another, normally an interchange between the three major types of rocks.
There are three major classification of rocks:
<h3>Sedimentary rocks </h3>
- Sedimentary rocks are types of rocks that are formed through accumulation of sediments at low temperatures in tectonic layers and sinks. These sediments includes; pebbles, shells, sand and other material fragments.
- The sediments accumulates in layers and then harden into rocks over a period of time.
- Examples of sedimentary rocks include; limestone and conglomerate
<h3>Metamorphic rocks</h3>
- These are types of rocks that are formed as a result of changes that occurs due to intense heat and pressure under the surface of the earth. They result from action of heat and pressure on other rocks that pre-existed.
- These types of rocks are characterized by shiny crystals, ribbon-like layers among other features.
- Examples of metamorphic rocks are marble and gneiss
<h3>Igneous rocks </h3>
- These are types of rocks that are formed as a result hardening and cooling of magma from volcanic eruptions. Magma may cool inside the earth or when on the surface of the earth as a result of volcanic eruptions. The lava from this eruptions cools and hardens to form metamorphic rocks.
- Igneous rocks are glass-like and shiny with no crystals. They may also have tiny spaces and holes due to gas bubbles trapped during the cooling process.
- Examples of igneous rocks include obsidian and basalt.
- The three types of rocks may be further classified in terms of chemical composition, texture and formation.
Key words: Rocks, types of rocks, chemical composition
