Answer
Organisms need to take food because they need to sustain their growth and reproduction. They use two main modes of nutrition, which are ingestion and assimilation. Ingestion is when an organism consumes food directly from the environment or another organism. Assimilation is when an organism absorbs nutrients from the environment and uses them to create new proteins, hormones, or other molecules.
Q.1. Why do organisms need to take food? NCERT CLASS-7th
Why do organisms need to take food?
Organisms need to take food because it provides them with necessary nutrients that allow them to grow and function. Some organisms, such as bacteria, use cellulose in their cell walls to extract glucose from their environment and produce energy. Other organisms, such as algae, use light energy to photosynthesis to create organic molecules such as glucose. Without these nutrients, most organisms would not be capable of completing their objectives.
What are two main modes of nutrition in organisms?
Two main modes of nutrition in organisms are body-based and LOC. Body-based nutrition occurs when an organism consumes food as part of its normal routine, such as eating and digesting food. LOC refers to the use of a specific nutrient source to maintain or improve health.

Why do organisms need food write three reasons Class 6?
Organisms need food to grow and reproduce. They use photosynthesis, which requires light energy to produce organic molecules from carbon dioxide and water. These molecules are used for the organism to create new cells, synthesize proteins and other molecules, and store energy.
Organisms also need food to survive. They eat bacteria or other organisms that live on the surface of rocks or in soil as well as other organisms that live in the body. These organisms provide the organism with nutrients that it needs to grow and reproduce.
What are the two modes of nutrition class 10?

Why is nutrition important for a living organisms Class 7?
The body is a complex system and needs nutrients to function properly. In order for an organism to survive, it needs to receive the right nutrients from the environment and from its own cells. The body’s nutrient requirements vary depending on the organism and its environment. For example, some organisms need more nitrogen than others, while others need more phosphorus. The ability of an organism to absorb these nutrients is critical for its survival.
What is nutrition class 6?
In the previous class we learned about what food groups are and how to make sure that our diet fits into one of those groups. This year, we will be focusing on nutrition class 6: Calories. In this class we will learn about how calories work, what different types of calories are, and how to calculate our own caloric intake.
What are the different modes of feeding in animals Class 7?

Why is nutrition necessary for an organism state three reasons Class 10?
One of the most fundamental questions in biology is why an organism exists. The answer to this question may lie in the chemical and metabolic state of the organism. In order for an organism to exist, it must have a certain chemical and metabolic state. This allows for the essential organelles, such as DNA and mitochondria, to function correctly.
Without these important elements, the organism would not live. Additionally, an organism’s state can be determined by how well it absorbs nutrients from its environment. If theorganism is not able to absorb nutrients properly, then it will become malnourished or deficient.
Finally, anorganism’s state also affects how it interacts with other organisms within its ecosystem. If one element is missing from an organism’s environment, then that organization will not be able to function properly in that area.
What is the mode of nutrition of human and other animals Class 7?
Human and other animals are classified according to their mode of nutrition. The mode of nutrition is the way in which an animal’s food is absorbed and used by the body. Animalmodeofnutrition is determined by the animal’s anatomy, diet, and environmental conditions.
Why do we need food very short answer class 6th?
Some people argue that we need food very short answer class 6th because it is difficult to get enough of necessary nutrients and vitamins.

Why do organisms need to take short answer?
In many cases, organisms need to take a short answer in order to understand complex questions. For example, scientists need to know how fast a virus moves so they can track it and prevent it from spreading. When studying genes, biologists also need to know what is expressed in each individual cell type in order to make informed decisions about how best to treat patients.
Why do organisms need food write two reasons in Brainly?
Organisms need food in order to survive and reproduce. There are two main types of food: physical and chemical. Physical food is like soil, grass, or other natural resources that organisms can harvest. Chemical food is like drugs, vaccines, or other treatments that organisms can use to fight off infections or ailments.
Physical and chemical food have different benefits for organisms. Physical food provides nutrients that help the organism to grow and reproduced. Chemical foods have side effects that can help the organism to fight off infections or ailments.
Both physical and chemical foods have some common benefits for organisms. For instance, both types of food provide energy for the organism. Physical foods also provide essential vitamins and minerals for the organism to function well. Chemical foods can help the organism fight off infections or ailments, but they also may have unintended consequences that can be harmful to the organism.
