Answer: 300J

Explanation:

Plants have 30000J from the sun.

Now..

rabbit gets 10% of the energy of plant .So this means that..

Deer- 10% x 30000=3000J

Now..

Tiger gets 10% of the energy of deer. So this means that..

Tiger-10% x 3000=300J

Hence tiger gets 300J of energy from the plant...

Energy Flow in the Food Chain

The energy flow in a food chain can be represented by the transfer of energy from one organism to another through the consumption of food. In this case, the food chain consists of plants, rabbits, and tigers.

Energy Capture by Plants

Plants are the primary producers in the food chain as they are capable of capturing energy from the Sun through the process of photosynthesis. It is mentioned that only 1% of the energy available from the Sun is trapped by the plants.

Therefore, if there are 30,000 joules of energy available from the Sun, the plants will be able to capture only 1% of that energy, which is 0.01 * 30,000 = 300 joules.

Energy Transfer to Rabbits

Rabbits are herbivores that feed on plants. When rabbits consume plants, they obtain the energy stored in the plant biomass. However, not all of the energy captured by the plants is transferred to the rabbits.

The transfer of energy between trophic levels in a food chain is typically around 10%. This means that only 10% of the energy available in the plants is transferred to the rabbits.

Therefore, the energy available to the rabbits from the plants can be calculated as 10% of the energy captured by the plants, which is 0.1 * 300 = 30 joules.

Energy Transfer to Tigers

Tigers are carnivores that feed on rabbits. When tigers consume rabbits, they obtain the energy stored in the rabbit biomass. Similarly, not all of the energy obtained by the rabbits is transferred to the tigers.

Again, the transfer of energy between trophic levels is typically around 10%. This means that only 10% of the energy available in the rabbits is transferred to the tigers.

Therefore, the energy available to the tigers from the rabbits can be calculated as 10% of the energy obtained by the rabbits, which is 0.1 * 30 = 3 joules.

Total Energy Available to the Tiger

In conclusion, if 30,000 joules of energy is available from the Sun, the total amount of energy available to the tiger in the given food chain is 3 joules. This demonstrates how energy is lost or transferred between trophic levels in a food chain, with each successive level receiving only a fraction of the energy from the previous level.
