Law of Cross-Cutting
Law of Old Age
Answer:
The law of Old Age is NOT one of Steno's Laws. Hope this helps!
Law of old age is not one of the Steno's Laws.
What is steno's law?In his law of stratigraphy, steno describes about pattern of deposition of rock layers. In 19th century, Nicolaus Steno was a geologist. He was the first to state that Earth's crust comprises a chronological history of geologic events. His four laws of stratigraphy are :
Law of superposition- It states that, younger layers of the rock formed on top of older layers. Law of original horizontality- It states that, deposition of layers of sedimentary rock are deposited flat.Law of crosscutting relationships- It states that, an intrusion (C) which disturbs rock layers (A) and (B) must not be older than rock layers. Law of lateral continuity- Until solid bodies block their deposition, layer of rocks are continuous.Therefore, law of old age is not given by Steno.

Explain the movement of initial energy from the sun through an energy pyramid.
Answer:
An energy pyramid is a model that shows the flow of energy from one trophic level to the next along a food chain. The pyramid base contains producers—organisms that make their own food from inorganic substances. Thus, the higher the trophic level on the pyramid, the lower the amount of available energy.
Even though it cannot be produced or destroyed, energy is emitted as heat at each level. Only 10% of energy is essentially transferred from one level to the next.
What energy from the sun through an energy pyramid?The amount of energy diminishes and the levels get smaller as you progress up the pyramid, via the trophic levels to primary, secondary, and tertiary consumers.
A figure that depicts the quantity and flow of energy transfer within an ecosystem is called an energy pyramid. The trophic levels of an ecosystem's food web serve as the basis for energy pyramids.
An energy pyramid is a diagram that depicts the movement of energy up a food chain from one trophic level to the next. Producers—organisms that create their own nourishment from inorganic materials—are found at the base of the pyramid.
Therefore, This means that the amount of available energy decreases with increasing trophic level on the pyramid.

Which of the following does the house cat have in common with a human?
A
order and species
B
kingdom, phylum and class
C
order, family and genus
D
kingdom, phylum, class and order
Answer:
B
Explanation:
humans and cats are in the same kingdom (animalia), phylum(chordata), class(mamalia)
Kingdom, Phylum and Class does the house cat have in common with a human. So, the correct option is (C).
What is Taxonomic hierarchy?Taxonomic hierarchy is defined as the process of arranging different organisms into successive levels of biological classification either in descending or ascending order from kingdom to species and vice versa.
Each level of the hierarchy is called a taxonomic category or rank where kingdom is always given the highest position which is followed by division, class, order, family, genus and species.
For above given information, Cat and human belongs to same kingdom i.e. Animalia, same Phylum i.e. Chordata and same Class i.e. Mammalia
Thus, Kingdom, Phylum and Class does the house cat have in common with a human. So, the correct option is (C).

C) A predatory fish is introduced into a lake, resulting in a dramatic decrease in the populations of smaller fish.
Explanation:
The other options wouldn't make sense because none of them would cause the extinction of a species. The animals would either adapt or only a few would die. If a new predatory fish were introduced into a lake that had never had it before, lots of the fish would die.

Environmental change has been consists many factors, such as the natural disaster, human interferences, or animal interactions. It has been also included physical change. Environmental change can also refers to the long-term shift in the temperature and weather patterns. These shifts may be the natural, such as through variations in the solar system.
In environmental change natural systems transform the sun's energy into living matter and cause changes by cycling material through geological, biological, oceanic and atmospheric processes. So environmental change has serious issue to our human society.

There are about 50 Orange-bellied Parrots remaining in the wild and a captive breeding population of around 320 individuals. The species is at risk of extinction in the wild in the near term. Current expertise suggests that habitat loss and degradation, particularly in the non-breeding range, has caused the decline.
