Most ecosystems on earth are powered by energy, which drives photosynthesis in plants and algae. 2. are elements required for growth and can affect the ability of an ecosystem to sustain life. 3. can be important in shaping terrestrial ecosystems by allowing animals to cool and even influencing the way plants grow. 4. In prairie grasslands, periodic is an important disturbance, allowing for certain plants to be triggered to grow. 5. limits the distribution of organisms that can survive in a given habitat based on how hot or cold it gets. 6. is essential to life because it makes up the majority of all cells.

0:00 Good morning.

00:01 Today we are going to study about ecosystem and its components.

00:05 What is an ecosystem? to define ecosystem, first let's see what are the components of an ecosystem.

00:14 The components of an ecosystem are two.

00:17 They are abiotic and biotic components.

00:25 So what are the abiotic components? it is also called the physical component or it is the physical.

00:31 Environment of a space that can be a land or water and it will comprise of the space defined as a land or water the air involved temperature weather weather weather wind light so on so all the abiotic components and the biotic components will involve both the plants and animals that are present in that area including the bacteria and other kind of all living organisms or all life in that space.

01:16 The relationship between the abiotic and the biotic components is defined by one single key component which is can be a living or a non -reuthers.

01:36 Living that is a biotic or a biotic component and that constitutes as an ecosystem.

01:46 For example in forest ecosystem tree makes the key component or the defining component of an ecosystem in an aquatic ecosystem it is water in a marine ecosystem it is the salt water or the salty nature of the water so thus these are the key components that defines an ecosystem so if i have to define ecosystem ecosystem are the physical and living components and that interrelationship at a unit of space with one key component defining the type of the ecosystem in all ecosystem living organisms are part of it and the living organisms will need energy to live and the energy is synthesized by the conversion of light to chemical energy and this process is known as photosynthesis and photosynthesis is carried out by organisms such as plants and algae that is all autotropes and the source of light is sun.

03:15 In other words, it is solar energy.

03:36 The elements needed for growth of life and the ability of the ecosystem to survive depends on this life and for which it needs...
