Questions and Answers

1.

The term Abiotic factors refers to.....
- A.
  
  Environmental influences produced other than by living organisms; for example, temperature, wind patterns, humidity, pH, substrate rock type, and other physical and chemical influences.
- B.
  
  None of the above
Correct Answer
A. Environmental influences produced other than by living organisms; for example, temperature, wind patterns, humidity, pH, substrate rock type, and other physical and chemical influences.

Explanation
Abiotic factors refer to environmental influences that are not produced by living organisms. These factors include temperature, wind patterns, humidity, pH, substrate rock type, and other physical and chemical influences. This means that abiotic factors are non-living components of an ecosystem that can significantly impact the organisms living within it.

The biosphere is divided in the...
- A.
  
  Lithosphere, atmosphere and dynosphere
- B.
  
  Lithosphere, atmopshere,
- C.
  
  Lithosphere, hydrosphere, atmosphere
- D.
  
  Hydropshere, atmosphere,
- E.
  
  None of the above
Correct Answer
C. Lithosphere, hydrosphere, atmosphere

Explanation
The biosphere is the part of Earth where living organisms exist. It includes all the ecosystems on the planet. The lithosphere refers to the solid outer layer of Earth, which includes the land and the Earth's crust. The hydrosphere includes all the water on Earth, including oceans, lakes, rivers, and groundwater. The atmosphere is the layer of gases that surround the Earth. Therefore, the correct answer is lithosphere, hydrosphere, atmosphere, as these three components make up the biosphere.

An example of an autotrophs is
- A.
  
  Geranium
- B.
  
  Bubble bee
- C.
  
  Lion
- D.
  
  Human
- E.
  
  Asian carp
Correct Answer
A. Geranium

Explanation
An autotroph is an organism that can produce its own food using energy from the sun or inorganic substances. Geraniums are examples of autotrophs because they can perform photosynthesis, converting sunlight into energy and using it to produce sugars for their growth and survival. This process allows geraniums to sustain themselves without relying on other organisms for food.

Which of the following is characteristic of parasitism?
- A.
  
  One organism kills and consumes another.
- B.
  
  Two organisms live together and neither is harmed.
- C.
  
  Two organisms feed side by side from the same food.
- D.
  
  Two organisms nourish each other; both benefit.
- E.
  
  One organism lives in or on another and benefits.
Correct Answer
E. One organism lives in or on another and benefits.

Explanation
Parasitism is a symbiotic relationship between two organisms where one organism, the parasite, lives in or on another organism, the host, and benefits from this relationship. The parasite obtains nutrients and shelter from the host, while the host is harmed or negatively affected. This characteristic is reflected in the given answer, "One organism lives in or on another and benefits."

The sequence of energy flow through a food chain is
- A.
  
  Primary consumers‑ producers‑ higher order consumers.
- B.
  
  Producers‑ higher order consumers‑ primary consumers.
- C.
  
  Higher order consumers‑ primary consumers‑ producers.
- D.
  
  Primary consumers‑ higher order consumers‑ producers.
- E.
  
  Producers‑ primary consumers‑ higher order consumers.
Correct Answer
E. Producers‑ primary consumers‑ higher order consumers.

Explanation
In a food chain, energy flows from producers (plants) to primary consumers (herbivores) and then to higher order consumers (carnivores or omnivores). Producers convert sunlight into energy through photosynthesis and are the primary source of energy in the food chain. Primary consumers obtain energy by consuming producers, and higher order consumers obtain energy by consuming primary consumers. Therefore, the correct sequence of energy flow is producers‑primary consumers‑higher order consumers.

In the carbon cycle humans act as a ....
- A.
  
  Source of carbon
- B.
  
  Reservour for carbon
- C.
  
  Agent for carbon
Correct Answer(s)
A. Source of carbon
C. Agent for carbon

Explanation
In the carbon cycle, humans act as a source of carbon because we release carbon dioxide into the atmosphere through activities such as burning fossil fuels and deforestation. Additionally, humans also act as agents for carbon as we play a role in transferring carbon between different reservoirs. For example, through activities like agriculture and land use changes, we can transfer carbon from the atmosphere to the biosphere or from the biosphere to the atmosphere.

All of the carbon in existence is continually recycled in the carbon cycle.
- A.
  
  True
- B.
  
  False
Correct Answer
A. True

Explanation
The carbon cycle is a natural process in which carbon is constantly exchanged between the atmosphere, oceans, plants, animals, and the Earth's crust. This means that all of the carbon in existence is indeed recycled in the carbon cycle.
