What do you mean by diversity in living organisms Class 9?
Our planet is gifted with numerous living organisms, which vary in their size, shape, habitat, nutrition, reproduction and a lot more. Based on their physical features and their habitat, these animals of Kingdom Animale are classified into different order and class.
What is the basis of classification Class 9 diversity in living organisms?
Answer: The basis of classification is: Type of cell (Eukaryotic or prokaryotic) Number of cells present (unicellular or multicellular)
What is meant by diversity of living organisms?
Biological diversity, or biodiversity, refers to all of the variety of life that exists on Earth. Biodiversity can be described and measured at three different levels: species, genetic, and ecosystem diversity. Species diversity refers to the number of different species in an ecosystem or on Earth as a whole.
What are the characteristics of living organisms Class 9?
Answer: Living things can reproduce, move on their own will, grow, have definite shape and size, have definite body organisation, respond to changes in the environment and perform excretion. However, non-living things do not have any of these characteristics.
Why is diversity of living things important?
Biodiversity is essential for the processes that support all life on Earth, including humans. Without a wide range of animals, plants and microorganisms, we cannot have the healthy ecosystems that we rely on to provide us with the air we breathe and the food we eat. And people also value nature of itself.
What is diversity in biology?
The term biodiversity (from “biological diversity”) refers to the variety of life on Earth at all its levels, from genes to ecosystems, and can encompass the evolutionary, ecological, and cultural processes that sustain life.
What are the sources of diversity in organisms?
Among other factors, the diversity of all living things (biota) depends on temperature, precipitation, altitude, soils, geography and the presence of other species. The study of the spatial distribution of organisms, species and ecosystems, is the science of biogeography.
What causes diversity in organisms?
Several factors contribute to species diversity, including habitat diversity, competition among species, and genetic diversity. Genetic diversity within a species not only is necessary to maintain diversity among species,6 but also contributes to the diversity of food, fiber, and medicines available from nature.
What are the three important features of living organisms?
Characteristics of living organisms are as follows:
- Definite shape and size.
- Organization (coordinated working of the body)
- Cellular organisation.
- Growth and repair.
- Spontaneous movement.
- Nutrition (taking in and utilising food substances)
- Respiration (energy released for body functions)
What are the 7 characteristics of a living organism?
There are seven characteristics of living things: movement, breathing or respiration, excretion, growth, sensitivity and reproduction. Some non-living things may show one or two of these characteristics but living things show all seven characteristics.
What is diversity and its importance?
1) Diversity drives creativity and innovation
Every culture, every nationality, every single person sees the world in a different way. Similarly, every culture, nationality, and person has different knowledge, perspectives, and points of view. When all of these different views are shared together, miracles can happen.
What is diversity with example?
Examples of diversity include visible diversity such as age, ethnicity, gender, physical abilities/qualities, race. Invisible diversity examples are sexual orientation, educational background, and work experiences. Personal diversity includes religion, geographical location, and general worldview.
What is the definition of diversity in biology?
Biological diversity refers to the global variety of species and ecosystems and the ecological processes of which they are part, covering three components: genetic, species and ecosystem diversity.
Why is diversity important in biology?
Biodiversity is essential for the processes that support all life on Earth, including humans. Without a wide range of animals, plants and microorganisms, we cannot have the healthy ecosystems that we rely on to provide us with the air we breathe and the food we eat.
Why is diversity important in the environment?
Biodiversity is the key indicator of the health of an ecosystem. A wide variety of species will cope better with threats than a limited number of them in large populations. Even if certain species are affected by pollution, climate change or human activities, the ecosystem as a whole may adapt and survive.
What is the smallest unit of life?
The cell is the smallest unit of life that can divide, multiply, grow and respond to stimuli from the environment.
What is the basic unit of life?
Cells
Cells are the tiny structures that make up all living organisms, including sharks, plants, cats, insects, bacteria, and you. People often say that cells are the basic building blocks of life.

What are the types of diversity?
There are generally four different types of diversity: internal, external, organizational, and worldview—and you should aim to understand and represent them all.
What are the effects of diversity?
Diversity enhances creativity. It encourages the search for novel information and perspectives, leading to better decision making and problem solving. Diversity can improve the bottom line of companies and lead to unfettered discoveries and breakthrough innovations.
What are types of diversity?

What are the benefits of diversity?
Better Decision-Making
Research showed that diverse teams are better at making decisions 87% of the time over non-diverse teams. Diverse teams offer broader perspectives and bring more information to the table. Teams outperform individuals when making decisions and that improves as diversity increases.
What cell is smallest?
mycoplasmas
As of today, the mycoplasmas are thought to be the smallest living cells in the biological world (Fig. 1). They have a minimal size of approximately 0.2 micrometers, which makes them smaller than some of the poxviruses.
