<span>A: food chain
</span><span>In many functions of a living organism, it cannot make its own energy. It uses energy from its environment, retrieves and converts into a usable and edible matter. Organisms that can do this process is the autotrophs, they can facilitate photosynthesis which they gather energy from the sun, water and carbon dioxide in order to create energy by then, the transfer of this energy to other organism is played by the food chain –food web. </span>
The correct answer to this question is this one: they lacked oxygen. The earliest organisms were completely heterotrophic in nature because of the reason that they lacked oxygen. <span>A heterotroph is an organism that cannot fix carbon and uses organic carbon for growth. </span>
Answer:
An acid is a substance or compound that releases hydrogen ions (H+) when in solution. In a strong acid, such as hydrochloric acid (HCl), all hydrogen ions (H+), and chloride ions (Cl-) dissociate (separate) when placed in water and these ions are no longer held together by ionic bonding.
Answer: by given steroid injection to animals

increasing production of cheap calories of Sugar and Triglycerides for use in food products
The attempt by farmers to maximize profit prompted them to give hormones e.g streroids to animals to increase their biochemical reactions therefore the the products yields e.g they are giving steroids to poultry to improve chicken, eggs production;and to cattle for improved beef and milk production.
In order to obtain maximum sugar and fats productions, cheap calories forms of there are being produced. e,g fructose, maltose. if maltose is consumed in excess it leads to obesity, while fructose increases the level of cholesterol.These products requires a lot of processing with different chemical products which leads to health problems after consumption
