<em>a. Cross-sectional study</em>
Explanation:
A cross-sectional analysis <em>includes at one particular point in time looking at data from a population.</em> Participants are chosen based on specific variables of interest in this type of study.
For developmental psychology, cross-sectional experiments are often used, but this approach is also used in many other fields, including social science and education.
The imbalance in energy would cause warming up of the planet and variety in fauna would be limited.
Explanation:
in an energy pyramid large amount of the energy gets dissipated only 10% of the energy is transferred to other level. Trophic level tells the placement of organism in a energy pyramid.
If at any time the pyramid gets blocked:
The passing of biomass and energy gets break to each level.
The organism at the higher level will be scarce of resources as nutrition and energy for growth, multiplication and metabolism.
The organisms at the higher level will get die eventually and vanish from the earth as no reproduction.
The energy dissipated will be in large amount disturbing the ecological chain.
The imbalance in energy would cause warming up of the planet and variety in fauna would be limited.
