Q

Serve as basic units of all life on earth

they are responsible for both the similarities and differences between organisms

A

GENES

19
Q
  • the variety of genes or inheritable characteristics present in a population

Chihuahuas, beagles, and Rottweiler’s are all dogs- but they’re not the same because their genes are different.

A

Genetic Diversity

20
Q

Variety of species within an ecosystem or habitat or a region (rainforests, coral reefs). Species are grouped together into families according to shared or similar characteristics

A

SPECIES DIVERSITY

21
Q

Defined as the number of different species present in an ecosystem and relative abundance of each of those species

A

SPECIES DIVERSITY

22
Q

Variety of ecosystems within a geographical location

A

ECOSYSTEM BIODIVERSITY

23
Q

FACTORS AFFECTING PHILIPPINE BIODIVERSITY

28
Q

a pattern of vertical layering in a forest community

A

Stratification

29
Q

It determine the nutrients such as nitrogen, phosphorus, sulfur, potassium, calcium, magnesium and micronutrients that are available for plants

A

30
Q

Protected and Regulated under blank, an Act providing for the conservation and protection of wildlife resources and their habitats, appropriating funds therefor and for other purposes.

Threatened plants are categorize as follows: Orchids, Ferns, Cycads, Medinillas, Molave for Bonsai, Tree Ferns, Alocacias, Begonias, Zingibers (wild gingers) and Agarwood

31
Q

What are the three (3) major types of ecological relationships in which communities are organized?

A

Predation
Symbiosis
Competition

32
Q

Members of two different species use the same limited resource and therefore compete for it

Competition negatively affects both participants (as either species would have higher survival and reproduction if the other was absent.)

EXAMPLE: predators of different species might compete for the same prey

A

Interspecific competition

33
Q

occurs between members of the same species.

Example: two male birds of the same species might compete for mates in the same area.

A

Intraspecific competition

34
Q

A member of one species (the predator) eats part of all of the living, or recently living, body of another organism (the prey- victim).

This interaction is beneficial for the predator, but harmful for the prey

It may involve two animal species, but it can also involve an animal, such as a mammal, bird, or insect consuming part of a plant, a special case of predation known as herbivory.

A

PREDATION

35
Q

A general term for interspecific interactions in which two species live together in a long-term, intimate association.

Close relationship between two organisms of different species in which at least one of the organisms benefits.

For the other organism, the relationship may be beneficial or harmful, or it may have no effect.

A

SYMBIOSIS

36
Q

Symbiotic relationship in which an organism from one species, called the parasite, benefits, while an organism from the other species, called the host, is harmed.

In parasitism, two species have a close, lasting interaction that is beneficial to one, the parasite, and harmful to the other, the host

A

PARASITISM

37
Q

Symbiotic relationship in which an individual from one of the species benefits while an individual from the other species is unaffected

A

COMMENSALISM

38
Q

Symbiosis refers to a close and prolonged association between two organisms of different species. Mutualism refers to mutually beneficial interactions between members of the same or different species.

A

MUTUALISM

39
Q

A linear sequence of organisms through which nutrients and energy pass as one organism eats another.

A

FOOD CHAIN

40
Q

The sequence of transfers of matter and energy in the form of food from organism to organism.

A

FOOD CHAIN

41
Q

Consist of many interconnected food chains and are more realistic representation of consumption relationships in ecosystems

Intertwine locally into a food web because most organisms consume more than one type of animal or plant.

In food webs, arrows point from an organism that is eaten to the organism that eats it.

A

FOOD WEB

42
Q

Is a biogeographic region that is both a significant reservoir of biodiversity and is threatened with destruction;

specifically refers to the 25 biologically rich areas around the world that have lost at least 70 percent of their original habitat

A

BIODIVERSITY HOTSPOT

43
Q

REPUBLIC ACT 9147

AN ACT PROVIDING FOR THE CONSERVATION AND PROTECTION OF WILDLIFE RESOURCES AND THEIR HABITATS, APPROPRIATING FUNDS THEREFORE AND FOR OTHER PURPOSES.

A

Wildlife Resources Conservation and Protection Act
