Answer:
There is no food web attached to this question but it can be answered because matter flows uniformly through trophic levels in all food webs.
The correct answer is;
A. matter from consumers, such as the green lynx spider, is eventually recycled by decomposers, such as a fungus.
Explanation:
A food web is an interconnected series of food chain showing how organisms feed on one another to obtain energy. A food web always start with a unique set of autotrophic organisms i.e. capable of producing their own food called PRODUCERS. Producers such as the cutleaf daisy in this question create the organic matter via the process of photosynthesis, which gets transferred to organisms that feed on them called CONSUMERS e.g green lynx spider
Consumers are heterotrophic i.e rely on other organisms for source of energy. As they feed on other organisms and get fed on, the matter gets transferred until the last consumer dies. The dead matter in the dead organism gets decomposed by organisms called decomposers e.g fungi and it gets recycled back into the soil as nutrients for use by plants.
Therefore, dead matter from consumers, such as the green lynx spider, is eventually recycled by decomposers, such as a fungus.
Answer:
In 1928, at St. Mary's Hospital, London, Alexander Fleming discovered penicillin. This discovery led to the introduction of antibiotics that greatly reduced the number of deaths from infection.
The discovery of penicillin was actually a mistake!
Fleming obtained an extract from the mold, naming its active agent penicillin. He determined that penicillin had an antibacterial effect on staphylococci and other gram-positive pathogens.
Explanation:
<h2><u>
Heart and lungs:</u></h2>
The upper chamber of the heart is called atrium and lower chamber of the heart is called ventricles.
The blood circulation in the heart is basically under the functioning of three blood vessels namely:
<h3><u>Arteries:
</u></h3>
- They start with the aorta, the huge vein leaving the heart.
- Veins divert oxygen-rich blood from the heart to the majority of the body's tissues.
- They branch a few times, decreasing and littler as they convey blood more remote from the heart.
<h3><u>Capillaries:
</u></h3>
- These are little; flimsy blood vessels that associate the arteries and the veins.
- Their dainty dividers permit oxygen, supplements, carbon dioxide, and other waste items to go to and from our organ's cells.
<h3><u>Veins:
</u></h3>
- These are the blood vessels that return blood to the heart; this blood needs (oxygen-poor) and is wealthy in waste items that are to be discharged or expelled from the body.
- Veins become bigger and bigger as they draw nearer to the heart.
- The unrivaled vena cava is the huge vein that brings blood from the head and arms to the heart, and the second rate vena cava brings blood from the mid-region and legs into the heart.
Genetic variation can be caused by mutation (which can create entirely new alleles in a population), random mating, random fertilization, and recombination between homologous chromosomes during meiosis (which reshuffles alleles within an organism's offspring).
