Substances that are not broken down by biological processes are said to be non-biodegradable. These substances may be inert and simply persist in the environment for a long time or may harm the various members of the ecosystem. For example, plastic.

When a substance Cannot be broken down to its chemical constituents through biological processes it is said to be?
Whereas the substance that cannot be decomposed by the natural decomposers and harm the environment is called as nonbiodegradable such as plastics, nuclear wastes or radioactive wastes, chemical wastes like DDT. Abiotic is the nonliving component of the ecosystem which consists air, water sunlight etc.
What do you mean by non-biodegradable material?
A Non-Biodegradable material can be defined as a kind of substance which cannot be broken down by natural organisms and acts as a source of pollution. Unlike biodegradable wastes, non-biodegradable cannot be easily handled. Non-biodegradable wastes are those that cannot be decomposed or dissolved by natural agents.
How do biodegradable materials affect the environment?
Biodegradable wastes pollute the environment only when they are in excess in the environment. Biodegradable substances affect the environment in the following ways: Biodegradable substances such as tree leaves, plant parts, and kitchen wastes can be used as humus after composting. This will enhance soil fertility.
Which is an example of biological process?
Examples of biological processes included in this category are cell growth and maintenance, signal transduction, pyrimidine metabolism, and cAMP biosynthesis.
Which of the following is a biological process?
the processes by which an organism has an observable effect on another organism of the same or different species. Also: cellular differentiation, fermentation, fertilisation, germination, tropism, hybridisation, metamorphosis, morphogenesis, photosynthesis, transpiration.
What do you call a substance that can be broken down through a nuclear reaction?
An atom is called “fissile” when the nucleus can be broken into two pieces under the impact of a neutron.
Which of the following Cannot be decomposed by chemical means?
Elements are chemically the simplest substances and hence, cannot be broken down using chemical methods.
Which of the following Cannot be broken down into simple substances?
Solution : An element cannot be broken down into simpler substances.
What are biodegradable examples?
- Human and animal waste. (Such as Fecal matter)
- Plant products such as wood, paper, food material etc.
- Remains of dead organisms.
- Egg shell.
Which one is biodegradable?
Biodegradable – Substances that are broken down by biological processes (with the help of some bacterias) are said to be biodegradable. Ex- paper, food products, cotton, cow dung, organic waste etc.
What is degradable and non degradable?
A material which gets decomposed through natural processes such as the action of bacteria is called biodegradable material. Examples: Peels of vegetables and fruits, wood. A material which is not easily decomposed by natural processes such as action of bacteria is called non-biodegradable material.
Which of the following is a biodegradable material?
Biodegradable materials are those materials that can be decomposed easily by bacteria or any other natural organism into simple molecules. Biodegradable materials are friendly to the environment and do not cause any pollution. Example: Woolen clothes, paper, peels of vegetables and fruits, cotton cloth, jute bag.
Which one of the following waste material is degradable?
Sources. Biodegradable waste can be found in municipal solid waste (sometimes called biodegradable municipal waste, or as green waste, food waste, paper waste and biodegradable plastics). Other biodegradable wastes include human waste, manure, sewage, sewage sludge and slaughterhouse waste.
What is another word for biological process?
•biological process (noun) organic process.
What are the biological processes of life?
The basic processes of life include organization, metabolism, responsiveness, movements, and reproduction. In humans, who represent the most complex form of life, there are additional requirements such as growth, differentiation, respiration, digestion, and excretion.
What is mean by process in biology?
A process is a naturally occurring or designed sequence of changes of properties or attributes of an object or system. In biology, it refers to any of the biological reactions or other events that result in a transformation or change from one state to another.
What causes biological processes?
Biological processes are in principle driven by chemical oxidation and reduction (or redox) reactions, that is, a coupling of two “half cells” through an exchange of electrons (see Appendix 1).
What is an important biological process?
Photosynthesis, the most important biological process on earth.
What are the 3 types of biological weathering?
- Burrowing animals. Soil formation is enhanced by many animals, from tiny one-cell organisms to the mammals that make a temporary or permanent home in soil.
- Organic material. Organic material is added to the soil from the decomposition of animals and plants.
- Lichens.
What are the 4 types of nuclear reactions?
- Fission.
- Fusion.
- Nuclear Decay.
- Transmutation.
What are the types of nuclear reaction?
Two notable types of nuclear reactions are nuclear fission reactions and nuclear fusion reactions.
Which term describes the conversion of substances into different substances?
chemical reaction, a process in which one or more substances, the reactants, are converted to one or more different substances, the products.
What can be broken down by chemical means?
A compound can be broken down by chemical reactions into simpler substances. For example, We can break water into constituent elements hydrogen and oxygen by electrolysis.
Which substance is decomposed by chemical means?
Compounds are pure substances formed by the combination of elements; they can be decomposed by ordinary chemical means.
