Answer
secondary consumers
Explanation
Secondary consumers are organisms which eat or depend on primary consumers. Primary consumers are those organisms that feed on plants, they are mainly herbivores and occupy second trophic level.-
Scavengers are organisms that mostly consume decaying organisms or matter, such as meat or rotting plant material. They are types of carnivores, which feed on meat, however, unlike carnivores which hunt and kill their prey, scavengers consume dead animals ad plants.
Secondary consumers occupy the third trophic level and include scavengers, other carnivores, and omnivores (consume both plants and animals).

Because of their chemical properties (hydrophobic lipid) these steroid hormones can pass through the plasma membrane and bind to their intracellular estrogen receptors in order to achieve their function ( modulate the expression of the genes).
Estrogen is the primary female sex hormone responsible for the development and regulation of the female reproductive system. It is also involved in the formation of secondary sex characteristics. Because of their roles, estrogenes are widely used as medications.
Multi cellular organisms are composed of many cells whereas unicellular organisms are composed of single cell. Multicellularity is indeed a progressive attribute of evolution where cells form tissue which forms organ and then organ system and finally an organism. Both multi cellular and unicellular organisms has advantages and disadvantages of their own. One of the main disadvantage of multi cellular organisms is that due to such a complex composition and functioning they require a large amount of energy for their maintenance and survival. Different organs and system require a huge amount of energy when it comes to comparison with unicellular organisms. A large amount of energy is also wasted in all these life processes. Though multi cellular organisms can survive in a variety of environmental conditions but then also their survival is difficult than any unicellular organism.
