Q

What is cellular respiration?

A

is the process by which cells in living organisms convert oxygen and glucose (sugar) into energy, releasing carbon dioxide and water as waste products.

Q

What is evaporation?

A

The sun heats up the water on land (lake river seas)
The water is turned into water vapour and absorbed into clouds

Q

What is precipitation

A

this coocurs when the droplets in the cloud become too heavy for the air to hold them, so they fall as precipitation (hall, rain, snow)

Q

What is the carbon cycle?

A
  1. The cycle of carbon on earth through photsynthesis and cellular respiration by all living things
  2. as well as the decomposition of dead organisms and waste products that have a heavy carbon content. decomposers would consume this

Q

What is fixation

A

The first step in the process of taking nitrogenout of the air and into the ground ready for ammonification

13
Q

Nitrofication?

A

Amoniam changes to nitrates by bacteria which plants are able to absorb

14
Q

Assimilation

A

Is the absorption of nitrates into plants through the roots

14
Q

Ammonification

A

When plants or animals die decomposers uses bactria and fungi to turn the nitrogen back into amoniam which re enters into the nitrogen cycle

15
Q

Denitrification

A

Extra nitrogen from the soil gets put back out into the atmosphere

16
Q

How does the relationship between organisms including prey and predator influence energy and matter in ecosystems?

A

Predators help control prey populations, preventing overgrazing and promoting species diversity. This regulation of prey populations influences the flow of energy and matter within ecosystems. When predators consume prey, energy and nutrients are transferred up the food chain, impacting the distribution of these resources and shaping the overall structure and functioning of the ecosystem.

16
Q

How does cellular respiration and photosynthesis involve the transfer of energy and matter?

A

Photosynthesis involves the convertion of carbon dioxide into oxygen and water and sunlight into glucose however cellular respiration converts glucose and oxygen into carbon dioxide and water crweating a cycle of energy matter being continously produced and absorbed

16
Q

Photosynthesis word equaiton?

A

Carbon dioxide + Water → Glucose + Oxygen

16
Q

Cellular respiration word equation?

A

glucose + oxygen → carbon dioxide + water + energy released

17
Q

WHat are natural greenhouse gases?

A

Naturally occuring greenhouse gases such as carbon dioxide (CO2), methane (CH4), and water vapor (H2O), play a crucial role in trappign the heat from the sun into the earths atmosphere (creatign a habitable temperature)

18
Q

WHat are artifical greenhouse gases?

A

Artifical gases are human produces greenhouse gases which intensify the greenhouse effect

18
Q

Descirbe the role ocean currents have in transferring energy?

A

They regulate earths temperature and weather, these currents also carry nutrients and food for marine life

18
Q

What causes ocean currents to move

A

Primarily riven by a combination of factors including wind, temp, salt and earths rotation

18
Q

What is global warming?

A

Long term increase in the earths average temperature due to the build up of greenhouse gases

19
Q

Explain how humansare causing the current climate change?

A

Burning of fossil fuels and deforestation are the main causes for climate change, By removing trees it limits the planets ability ot absorb CO2

19
Q

Evidence of global warming?

A

Extreme weather events
Rising Sea Levels

20
Q

What are cyclones?

A

Cyclones are formed when the ocean is warm moist air rises and wind patterns increase they contain heavy rainfall, storm surge and destructive winds.

21
Q

What are convection cells?

A

Large scale convection within the earths core

21
Q

identify the human impacts on ecosystems how they alter the balance in ecosystems

A

Habitat destruction - through urbanization and deforestation reduces biodiversity
Pollution - contaminate air, water, and soil, harming both plants and animals.
Overexploitation - overfishing and excessive hunting, can deplete species populations
Climate Change - alters temperature and precipitation patterns,

22
Q

What is the quadrant mehtod?

A

Abundance = average number per quadrat x total area

divided by area of the quadrat

23
Q

describe a method for measuring a chnage in abiotic factors and how a change in the abiotic factor could impact an ecosystem?

A

method = environmental monitoring, which involves collecting data on various factors such as temperature, pH, and nutrient levels.
temperature increases from climate change can lead to shifts in species distribution, disrupting the ecosystem’s balance. Changes in nutrient levels can trigger harmful algal blooms, harming aquatic life.
