28
Q

Whats the energy flow of the food chain and the food web?

A

The energy flow is that one trophic level goes to the food chain and then goes to the next.

29
Q

What is Photosynthesis?

A

Process plants uses to make energy.

30
Q

Cellular Respiration means?

A

Process by which all living things break down sugar and then turn into energy.

31
Q

What are the 5 Nutrients Cycles?

A

Carbon Cycle, Nitrogen Cycle, Oxygen Cycle, Sulfur Cycle, and Water Cycle.

32
Q

Biotic Interactions mean?

A

Biotic interactions refer to the relationships among organisms. They can be intraspecific (between members of the same species) or interspecific (between members of different species). When at least one of the interactants is harmed, the relationship is called an antagonism.

33
Q

Symbiosis means?

A

close interaction b/w two different species living in the same area

34
Q

mutualism?

A

both organism benefit

35
Q

commensalism?

A

one organism benefits while the other is unaffected

36
Q

parasitism?

A

one organism benefits while the other is harmed

37
Q

predator and prey relationships?

A

A predator is an organism that eats another organism. The prey is the organism which the predator eats.

38
Q

closed population means

A

A closed population has a constant membership; there are no births, deaths, or migration into or out of the population during the sampling period.

39
Q

open population means?

A

pen populations are more common than closed populations since most groups of organisms are able to exchange members at least periodically.

40
Q

natality means?

A

the ratio of the number of births to the size of that population.

41
Q

mortality

A

the death rate.

42
Q

immigration

A

an animal establishes a home in a habitat because it has resources it can utilize or because the habitat is ideal for them.

43
Q

emigration

A

an animal leaves its home because the habitat is no longer ideal for them and they need to find a more suitable environment.

44
Q

carrying means?

A

species’ average population size in a particular habitat.

45
Q

capacity means?

A

the amount of liquid a container can hold

46
Q

equilibrium?

A

the state of being balanced, where opposing forces cancel each other out and no changes are occurring.

47
Q

what is the definition of acid rain?

A

acid rain pollutants containing nitogen and sulphur that combines with water vapour in the air that forms acid rain.

48
Q

native species?

A

An organism living naturally in its environment without human intervention

49
Q

non-native species ?

A

Organism that has been introduced by human action, either accidentally or deliberately, outside of its natural range.

50
Q

invasive species?

A

Organism that has been introduced by human action, either accidentally or deliberately, outside of its natural range.

51
Q

coral bleaching?

A

Coral & algae display mutualism.
The algae photosynthesize and provide food (sugar) for the coral & gives coral its colour.
When coral become stressed, the algae leaves the coral and results in white coral. 🙁
Bleached coral have no food source and often die. 😢

52
Q

heavy materials

A

metal elements that have are very dense (heavy) and are toxic at low concentrations

53
Q

biomagnification means ?

A

process that causes higher organisms in the food chain to have greater concentration of toxins

54
Q

Aggressive Plants

A

Plants that spreads easily because it is planted in its ideal growing conditions.
Native plants can be aggressive because they grow quickly but don’t harm the environment
Invasive plants are always aggressive.

55
Q

ex-situ conservation

A

onserves species by removing them from their natural habitat → last resort strategy!

56
Q

in-situ conservation

A

conserves species in their natural habitat

57
Q

Ecological footprint?

A

an estimate of how much land and water is needed to support your lifestyle.

58
Q

Environmental stewards?

A

those who take care of our natural resource to ensure that they are used in sustainable ways for future generations

59
Q

Organic farming?

A

no chemical fertilizers or pesticides. However, not able to produce the same amount of food as non-organic farming

60
Q

no till farming?

A

leaving the stubble/roots of last year’s crops in the soil and planting new crops among the stubble. However, not all crops can be grown this way

61
Q

Crop rotation

A

he practice of growing different crops at different times on the same land in order to preserve nutrients in soil

62
Q

biological control?

A

the use of beneficial insects to control unwanted pests

63
Q

Which process occurs in plants?

A

photosynthesis and cellular respiration happens in plants. Photosynthesis only happens during the day, while cellular respiration happens during both the day and at night.

64
Q

ph levels and causes?

A

measures the acidity levels of a substance
pH of 7 is neutral
low pH (<7), it is acidic
high pH (>7), it’s alkaline (basic)
