How do plants and animals obtain energy
Interdependence of plants and animals class-5
Energy is required for all living organisms to develop and reproduce, sustain their structures, and react to their surroundings. Metabolism is a series of life-sustaining chemical processes that enable organisms to convert chemical energy stored in molecules into energy for cellular processes. Animals eat to refuel their bodies, and their metabolism breaks down carbohydrates, lipids, proteins, and nucleic acids to provide chemical energy for these processes. Photosynthesis is the mechanism by which plants transform solar energy into chemical energy stored in molecules.
Difference between plants and animals – living things
Scientific inquiry must be incorporated in science education in order to link scientific knowledge and practices and inspire students to learn through exploration. Although there are several types of inquiry-based models, the FERA Learning Cycle, developed by the National Science Resources Center (NSRC), is one that I’ve come to appreciate and use:
I love how the Institute for Systems Biology’s Center for Inquiry Science describes that this is “not a locked-step procedure,” but rather “a cyclical process,” with some lessons starting at the focus phase and others at the explore phase.
Finally, How Inquiry-Based Learning Works with STEM, a fantastic article on Edudemic.com, explains how inquiry-based learning “paves the way for successful learning in science” and promotes College and Career Readiness, especially in the field of STEM career options.
Students will learn about the biotic and abiotic factors that affect ecosystems, the characteristics and classification of living organisms, and how plants and animals get and use energy to meet their needs in this unit.
Plants and animals – similarities and differences
To serve all of their biochemical needs, plants only need light, water, and about 20 elements, which are referred to as essential nutrients. Three requirements must be met for an element to be considered essential: 1) The element is needed for the plant to complete its life cycle; 2) no other element can perform the element’s function; and 3) the element is directly involved in plant nutrition.
About thirty percent of plant matter is made up of cellulose, the main structural component of the plant cell wall. It’s the most common organic compound on the planet. Plants can make their own cellulose, but they use carbon from the atmosphere to do so.
Another macromolecule, phosphorus (P), is needed for the production of nucleic acids and phospholipids. Phosphorus is a component of ATP that allows food energy to be converted into chemical energy through oxidative phosphorylation. Similarly, during photophosphorylation in photosynthesis, light energy is converted into chemical energy, which is then extracted during respiration. Phosphorous is usually available in a form that isn’t easily absorbed by plant roots; the bioavailable form is present in limited amounts and quickly “fixed” back into the bioavailable form. As a result, phosphorus is frequently a limiting factor for plant development.
Food for plants and animals
One or more cells make up every living organism on the planet. Each cell is driven by chemical energy found primarily in carbohydrate molecules (food), with photosynthesis accounting for the vast majority of these molecules. Certain organisms transform solar energy (light) into chemical energy, which is then used to create carbohydrate molecules, through photosynthesis. When an organism breaks down food, the energy used to keep these molecules together is released. The energy is then used by cells to perform tasks such as cellular respiration.
Photosynthesis-derived energy reaches our planet’s habitats on a continuous basis and is passed from one individual to another. As a result, photosynthesis provides the majority of the energy provided by living things on Earth, whether directly or indirectly.
Some species have the ability to photosynthesise, while others do not. An autotroph is a living organism that can feed itself. The term autotroph comes from Greek roots that mean “self” (auto) “feeder” (troph). Plants are the most well-known autotrophs, but there are others, such as bacteria and algae (Figure 5.2). Global food chains benefit greatly from the abundance of food and oxygen provided by oceanic algae. Plants are also photoautotrophs, a type of autotroph that synthesizes chemical energy in the form of carbohydrates using sunlight and carbon dioxide. Photosynthesis is needed by all living organisms.
