I believe the answer is chromosome or dna
The most likely basis for future human evolutionary change is technological change.
Evolution is a natural process that takes millions of years to occur. In this, an organism evolves on the basis of changing environment, living conditions, availability of food, living place and pattern, etc.
Natural selection works as an important force in this process as nature selects the fittest individuals which means nature selects those individuals who have the most appropriate genes according to the current conditions for survival to reproduce and pass those genes to the next generation.
The differences in the genes depend on an individual's ability to adapt to the changes in the environment and change their living style and habits accordingly to survive.
Therefore, in the current scenario, technology is heading to be the world leader and humans have to learn to adapt to the changes accordingly and evolve in the same way so that they better fit with the coming changes and can survive easily.

Answer:
first level consumers?- abou 100 units
Second level consumers- about 10 units
Third level of consumers- about 1 unit
Explanation:
Food chain describes the feeding pattern of a group of organisms in an ecosystem. The food chain shows how one organism in one TROPHIC LEVEL feeds on another organism in another. As organisms are being fed on, energy is being transferred.
A food chain always starts with a PRODUCER, which occupies the first and lowest trophic level. It creates the energy transfer as it obtains energy via photosynthetic process. The flow of energy as shown by an energy pyramid is Producer----First level consumer----Second level consumer------Third level consumer.
However, only about 10% of the available energy is transferred and accessible by the next organism. This is because about 90% of the energy has been lost as heat when the organism undergoes metabolic processes. Hence, if 1000 units of energy was present at the producer level, 10/100 × 1000= 100 units will be available to first level consumers.
Also, 10/100 × 100= 10 units of energy will be available to second level consumers and finally 10/100 × 10= 1 unit of energy will be available to talk third level consumer.
