In photosynthesis, plants convert solar energy into glucose, which is later consumed as universal food. Each plant utilizes the sun’s energy to make glucose and oxygen while also absorbing carbon dioxide from the atmosphere through its leaves, absorbing water through its roots, and absorbing sunlight. We will further discuss the two primary sources of energy that power living systems and their trophic levels. We will also answer the question what do consumers use as a source of energy.
1. List Two Primary Sources of Energy that power Living Systems
The two primary sources of energy that power living systems are:
- Photosynthesis – It is a process in which plants derive energy from the sun and it is used to help them make food. These plants are then consumed by the herbivores to gain energy and nutrients.
- Chemosynthesis – It is the process where the bacteria and microorganisms make glucose with the help of the chemical source of energy due to the lack of sunlight. Similar to how plants use photosynthesis to capture solar energy, deep-sea animals use chemosynthesis to capture and create energy.
Remember that similar to the process of photosynthesis, bacteria use chemicals rather than other energy sources. Where there is little or no sunlight surrounding hydrothermal vents in the deep water, this process occurs.
2. What do Consumers use as a Source of Energy?
Consumers take the second trophic level. They have producers as they cannot make their food. They get energy from plants or other animals and some eat both. Must see What would Happen in an Ecosystem without Herbivores?
3. How do Living Things get Energy from the Sun?
Every living organism in this world needs sunlight. Plants need sunlight to grow. Animals and humans need plants for the food and oxygen they produce. The heat of the sun is so important and without it the earth would freeze. There would be no winds, clouds, or water. How do living things get energy from the sun? Take a look:
- Plants: The sun is a source of energy for plants. They derive energy from the sun and take carbon dioxide from the air and water to make glucose. Plants have vitamin D which is important for animals, and they absorb sunlight.
- Animals: Animals also get benefitted from the sun’s energy. This happens when the energy from the sun is transferred from plants to animals. Our skin also produces vitamin D, which is important for strong bones. Animals get vitamins after eating those green plants.
4. What are the Primary Energy Example?
Primary energy is an energy source that is found in nature and which cannot be transformed. It is the kind of energy that has raw fuels and other forms of energy received in the original form. Primary energy can be taken from renewable and non-renewable sources. Eg: the radiation of the sun. This is also included in the list other than the two primary sources of energy that power living systems. (See How do solar powered lights work?)
5. What is the Difference between Renewable and Non-Renewable Sources of Energy?
- Renewable – Renewable sources of energy can be used multiple times after continuous consumption. Examples are sun, wind, and tidal energy.
- Non–Renewable – The sources which cannot be easily replaced as they are available in a limited quantity, are called non-renewable resources. Examples of non-renewable sources of energy are fossil fuels, coal, petroleum, and natural gas.
6. What is the Source of Energy for Deep Ocean?
In addition to the two primary sources of energy that power living systems, there are three main sources of energy and nutrients for the deep sea which are marine snow, whale falls, and hydrothermal vents.
7. How is Electricity generated?
The United States has so many energy sources and technologies for generations of electricity. There has been a lot of evolution since the industrial revolution. The three major sources of energy generation are fossil fuels and nuclear biomass. (See What is Sustainability and Why is it Important?)
8. What are the Sources of Food Energy?
The sources of food energy are proteins and carbohydrates, which are consumed by both plants and animals.
9. What is Wind Energy?
Wind energy is electrical energy obtained from wind by using windmills or turbines. Wind energy has so many benefits and is the fastest-growing energy source in the world. In the future, it will overcome the problems associated with other forms of energy. (See Which Instrument is used to Measure Wind Speed?)
10. What is Fossil Fuel?
It is a natural fuel that is formed in the earth’s crust using the remains of dead plants and animals. Fossil fuels are very important for human survival and are also a primary source of energy. They are important for heating, transportation, and the generation of electricity which creates products like computers, paint, and other household appliances.
