A nutrient is a chemical substance that an organism needs to perform life processes. An organism obtains nutrients from its environment. The bodies of all organisms are built from water and nutrients. Common nutrients include carbon, nitrogen, and phosphorus.
Is a substance used by an organism to survive?
A nutrient is a substance used by an organism to survive, grow, and reproduce. The requirement for dietary nutrient intake applies to animals, plants, fungi, and protists.
What is an organism that uses chemical or light energy to produce its own food supply?
An autotroph is an organism that can produce its own food using light, water, carbon dioxide, or other chemicals. Because autotrophs produce their own food, they are sometimes called producers.
Is a chemical substance which alters the speed of a chemical reaction?
A catalyst is a substance that alters the rate of a chemical reaction but remains chemically unchanged afterwards. The catalyst increases the rate of the reaction by providing a different reaction mechanism to occur with a lower activation energy.
Is carbon a cycle?
The carbon cycle is nature’s way of reusing carbon atoms, which travel from the atmosphere into organisms in the Earth and then back into the atmosphere over and over again. Most carbon is stored in rocks and sediments, while the rest is stored in the ocean, atmosphere, and living organisms.
What are living organisms?
An organism refers to a living thing that has an organized structure, can react to stimuli, reproduce, grow, adapt, and maintain homeostasis. An organism would, therefore, be any animal, plant, fungus, protist, bacterium, or archaeon on earth.
What are the living things in the ecosystem?
Biotic factors or living parts of the ecosystem include animals, plants, fungi, protists, and bacteria. Plants and algae are called producers. They produce oxygen and food that animals need. Animals are called consumers.
Why do living things need living space?
Space is another critical basic need; organisms such as plants and fungi that are anchored to a substrate need a certain amount of space in which to grow and thrive. Animals and other organisms that can move need living space as well as territory in which to search for food and mates.
What organism does not require sunlight to live?
There are bacteria that live in hot springs and other volcanic water that get their energy from chemicals released as a result of volcanic activity. They do not need light, and they do not need oxygen, and the Earth’s interior provides them with heat, so they can live without the sun.
Which of the following living organism uses sunlight to make its food?
Answer: plants because they are autotrophs they use sunlight to prepare their own food.
What energy is needed by organisms during cell respiration?
Adenosine Triphosphate(ATP) energy is needed by organisms during cell respiration. Explanation: Adenosine Triphosphate(ATP): Adenosine Triphosphate (ATP) is the primary energy carrier in all living organisms on earth.
What are the substances created during a chemical reaction called?
The substances that go into a chemical reaction are called the reactants, and the substances produced at the end of the reaction are known as the products.
Is a chemical reaction is a temporary reaction?
A chemical reaction is a temporary reaction- False. Correct statement: A chemical reaction is permanent.
What type of reactions release energy or heat?
Exothermic reactions are reactions or processes that release energy, usually in the form of heat or light. In an exothermic reaction, energy is released because the total energy of the products is less than the total energy of the reactants.
Which type of energy is used by living organisms?
The form of energy that living things need for these processes is chemical energy, and it comes from food. Food consists of organic molecules that store energy in their chemical bonds.
Why do living organisms require an outside source of materials and energy?
Living organisms must take in energy via food, nutrients, or sunlight in order to carry out cellular processes. The transport, synthesis, and breakdown of nutrients and molecules in a cell require the use of energy.
Where do most living things get the energy they need for life?
Most energy comes from the sun, either directly or indirectly: Most life forms on earth get their energy from the sun. Plants use photosynthesis to capture sunlight, and herbivores eat those plants to obtain energy. Carnivores eat the herbivores, and decomposers digest plant and animal matter.
