a) In a food chain, arrows show the movement of nutrients or energy from one organism to another. It refers to the direction of transfer of energy or nutrients from the organism being consumed to the organism consuming it.

b) The producer in the diagrammatic food chain is lettuce, followed by green fly, ladybug, thrush and cat. Producers—also called autotrophs—are living things that can make their own food through photosynthesis or chemosynthesis, the process by which sunlight or inorganic substances are converted into energy-rich organic molecules.

c. Ladybird is the third trophic level of the food chain. The term "trophic level" describes the place an organism occupies in a food chain or web, from where it obtains its food and energy. In this scenario the greenfly is the primary consumer at the second trophic level, while the ladybird is the secondary consumer at the third trophic level. Lettuce is the first trophic level in this scenario (producer).

d.Cat is the third largest consumer in the provided food chain. In a food chain or web, tertiary consumers are those species at the highest trophic level. Typically, they are carnivores that prey on other carnivores or secondary consumers.

e) Sun is the primary energy source that powers the food chain. Most ecosystems get their energy mostly from the sun. As the species consumes and is consumed by other organisms, it is passed along the food chain after being captured by producers (such as plants) through photosynthesis.

Answers

Answer:

Interphase is the longest and metaphase is the shortest usually

Explanation:

Answer

The longest phase of the cell cycle is Interphase

The shortest phase of the cell cycle is the Mitotic phase

Explanation

In case of cells with a nucleus, the stages of the cycle are divided into two phases: Interphase and the Mitotic (M) phase.

During Interphase the cell grows and makes a copy of its DNA before moving into Mitosis.

During Mitotic phase the cell separates its DNA into two sets to create two genetically identical daughter cells.

Answer:

From plant reproduction.

Explanation:

Plants produce flowers to make seeds. To make a seed a flower must be pollinated. Pollen from the male part of one flower travels to the female part of another flower where the seeds are made. Most, but not all plants, have both male and female parts inside one flower. The stigma is usually in the centre and the stamens, which produce the pollen, cluster around it. The petals act like an advertisement to attract various animals, which will carry the pollen from one flower to another.

Dilution is necessary during pure culture preparation to reduce the bacterial load and allow readable colonies to grow.

Dilution of bacteria culture is carried out in comparison to McCfarlan standard so as to have a decent number of bacteria that will not be too numerous or too little to observe the growth of distinct colonies during culture preparation.

Without dilution, colonies may form but may be too numerous to count. Too much dilution may also lead to no growth in the culture plates.

Perhaps the biggest mystery is whether it is convincing evidence or a simple desire to believe that keeps the myth alive.Loch Ness is a lake in Scotland. The loch, or lake, is known for sightings of a mysterious monster. Most who see this monster, known as Nessie, describe something with a long neck and several humps above the water. Sometimes the "monster" is moving in these sightings, and sometimes it is still. Many have suggested that Nessie might be a plesiosaur (plea-see-a-soar), an aquatic dinosaur that was trapped in the loch after the last ice age.The plesiosaur theory presents several problems. First, the plesiosaur is an air breather. Such a creature would need to surface often and, therefore, be seen more frequently. Second, it's unlikely that the same creature has lived in the loch since the last ice age. Today's creature would have to be the offspring of an original plesiosaur trapped long ago. This would suggest multiple creatures in the loch (needed to produce offspring). Again, sightings would be more frequent if this were the case.So from a purely logical stand point, the existence of such a large and ancient creature is unlikely. But assume for a minute that it is possible. What would a plesiosaur need to live in an enclosed lake?Tropical waters: Scientists believe plesiosaurs were warm-blooded. Like crocodiles and alligators, plesiosaurs would need to live in warm waters. The loch is very cold with temperatures averaging about 40 degrees Fahrenheit (4.4 Celsius).Food: Like other warm-blooded creatures, plesiosaurs would need a large quantity of food. If there is a group of Nessies, then even more food would be needed. Because the loch is full of silt (underwater dust) not much light gets into the deepest areas. So the food chain, which would depend on plankton, is very weak at its base. As a result, there is probably not enough food to support such a large creature.However, the plesiosaur theory is not the only one. Many other ideas attempt to explain the sightings and "photographs." But two separate sonar surveys of the loch have not found any evidence of a creature larger than a salmon. The last survey,1 completed in 2007 by the British Broadcasting Company (BBC), involved 600 different sonar beams. Using satellite navigation systems, the team made sure every inch of the loch was searched. The team found nothing.With cell phones and digital cameras, one would think that sightings of Nessie would increase. This has not happened. The BBC team believes the legend of Nessie has endured because people see what they want to see. To prove this, the team used a fence post, raising it before groups of tourists. Afterwards several of the tourists asked to draw pictures of what they had seen drew pictures of a monster's head.Based on the text, what is the main result of scientists having studied the plesiosaur?A. The people who claim to have seen Nessie can be proven to have been dishonest.B. The sightings have decreased rapidly since the studies were released. C. We can conclusively rule out the existence of modern plesiosaurs. D.We know enough to rule out a plesiosaur as a likely Nessie creature.
