Answer:
The two components are biotic and abiotic components
Explanation:
The two components essential for the functioning of the ecosystem are:
Biotic Components:
These are the organic components like plants, pathogens, animals, human beings and other living components in the ecosystem that affects other living organisms, influences them and helps in shaping the ecosystem.
they require desired amount of nutrition and energy and energy for proper everyday functioning.
They are further classified as Producers, decomposers and consumers out of which producers prepare their own food by photosynthesis where consumers fulfills their requirement from producers and decomposers depend s on both producers and consumers for chemical breakdown into simpler and reusable forms.
Abiotic Components:
These are the inorganic components of the ecosystem like humidity, temperature, etc.
These are the non living components of the ecosystem which includes physical and chemical constituents of the environment which influences the biotic components and the ecosystem's functioning.
The abiotic components influences certain behaviors in living organisms like reproduction, growth, etc.
These components are synthesized by the process of photosynthesis by utilizing sunlight to convert these into organic compounds by primary producers which are further are the consumption of secondary producers thus increasing the organic content.

The upward force exerted on the board by the support is mathematically given as
Fu= 764.8 N
<h3>What is the upward force exerted on the board by the support?</h3>
Generally, the equation for is mathematically given as
Considering that the Net Force on the system is null
The weight of the children plus the weight of the board equals the upward force imposed on the support.
The upward force
Fu= 440 + 272 + 52.8 N
Fu= 764.8 N
In conclusion, he upward force exerted on the board by the support
Fu= 764.8 N

<u>Order sequence of steps that are involved in the production of work by a four-stroke heat engine as follows:
</u>
- Piston moves down, allowing fuel-air mixture to enter intake valve
- Piston moves up, compressing gas and causing gas to increase its temperature
- Combustion as gas is still compressed; increase in energy from combustion pushes piston down
- Piston moves up, pushing burned gases through exhaust valve: Spark plug fires, causing
Answer: Options D, A, C and B
<u>Explanation:
</u>
There are four basic steps of a four stroke engine- Intake, Combustion, Power and Exhaust. The first step is the intake of air plus fuel mixture in the combustion chamber. At this time, the piston moves down. Now when the chamber is closed, the spark plug ignites fire which expands the fuel gases.
The gases push down, piston and crankshaft rotates in this way. Once the gases the combustion is done, there is plenty of space in the chamber that makes the piston moves up. In this way a complete cycle is completed and the crankshaft moves. That’s the working of this four stroke engines.
Answer:
time taken is equal to 14,156 years
Explanation:
we know,
at t = 0
Y(0) = A
given that half life of plutonium 239 = 24,200
hence time taken is equal to 14,156 years
