<span>"Never, development continues throughout life". thats why i put on a test and got it right</span>
Why is the pulmonary circulation reduced in the human fetus? Pulmonary circulation is reduced in the human fetus because the baby gets its oxygen from its mother and does not breath on its own.
The parts that interact to form a whole ecosystem include
Abiotic Components
The abiotic components of an ecosystem are all of the nonliving elements. They include the water, the air, the temperature and the rocks and minerals that make up the soil. Abiotic components of an ecosystem might include how much rain falls on it, whether it is fresh water or salt water, how much sun it gets or how often it freezes and thaws. The biotic components of the ecosystem both live on and interact with the abiotic components.
Producers at the Base
Producers are the living organisms in the ecosystem that take in energy from sunlight and use it to transform carbon dioxide and oxygen into sugars. Plants, algae and photosynthetic bacteria are all examples of producers. Producers form the base of the food web and are generally the largest group in the ecosystem by weight, or biomass. They also act as an interface with the abiotic components of the ecosystem during nutrient cycles as they incorporate inorganic carbon and nitrogen from the atmosphere.
Consumers in the Chain
Consumers are living organisms in the ecosystem that get their energy from consuming other organisms. Conceptually, consumers are further subdivided by what they eat: Herbivores eat producers, carnivores eat other animals and omnivores eat both. Along with producers and decomposers, consumers are part of what is known as food chains and webs, where energy and nutrient transfer can be mapped out. Consumers can only harvest about 10 percent of the energy contained in what they eat, so there tends to be less biomass at each stage as you move up the food chain.
Decomposers and Nutrient Cycling
Decomposers are the living component of the ecosystem that breaks down waste material and dead organisms. Examples of decomposers include earthworms, dung beetles and many species of fungi and bacteria. They perform a vital recycling function, returning nutrients incorporated into dead organisms to the soil where plants can take them up again. In this process they also harvest the last of the sunlight energy initially absorbed by producers. Decomposers represent the final step in many of the cyclical ecosystem processes.
The bloomers fashion included an amalgamation of dress and trousers as a fashion trend during the height of civil rights clamor. The clothes were castigated by men for they feared a reversal of gender roles. Only men were allowed to wear trousers during the time.
Answer:
Biological evolution
Explanation:
<em>Biological evolution is defined as the formation of complex organisms from single ancestral type over a large time period. Evolution believes that all living organisms descended from a common ancestor but not without modification.</em>
There are several evidence to support the theory of evolution including morphological evidence, paleontological evidence, biochemical evidence, among others.
The similarity in the structure and components of DNA of all living organisms is one of the evidence pointing to the fact that living organisms might truly have been from a common ancestor. In addition, all living organisms tend to use ATP largely as their source of energy, giving further credence to evolution theory.
