When a community begins with bare rocks and no living organisms, it is called _________?
5
When a community begins with bare rocks and no living organisms, it is called Primary Succession?
6
There are two types of behavioral adaptations….what are they?
7
There are tow types of behavioral adaptations….what are they? Learned (think of a pack of dogs) Instinctual (think hibernation)
8
Large teeth in a shark or feathers on a bird are examples of____ adaptations.
9
External Structural
10
Large teeth in a shark or feathers on a bird are examples of____ adaptations. Structural
11
Fish gills are internal structural adaptations which help them _________
12
Fish gills are internal structural adaptations which help them Breath (Gas exchange)
13
Forest fires, wind storms, or human activates that greatly alter an environment are what type of succession?
14
Forest fires, wind storms, or human activates that greatly alter an environment are what type of succession? Secondary Succession (where small plants will grow back)
15
What would be a trait of a small animal that spends its entire life in a cave in the dark (troglobites)?
16
-Poorly developed vision -Lack of pigment -Highly developed sense organs like antenna.
17
How much mass is there?_______
18
How much mass is there? 347 Grams
19
Why would finches need to develop different shapes for their beaks?
20
Their beaks are adapted to the type of food they eat (bugs, seeds, etc)
21
How could a small mammal adapt to a cold environment (besides hibernation)?
22
They could grow thick long fur that would keep them toasty in the cold weather.
23
How could a small mammal adapt to a cold environment (besides hibernation)? They could grow thick long fur that would keep them toasty in the cold weather.
24
Which Biome would a cactus best be adapted for?
25
Which Biome would a cactus best be adapted for? A Desert biome
26
For an ecosystem to be sustainable, it would require (high or low) biodiversity?
27
For an ecosystem to be sustainable, it would require (high or low) biodiversity? High Biodiversity
28
Hunting, destruction of forest and pollution result in (higher or lower) biodiversity?________________
29
Hunting, destruction of forest and pollution result in (higher or lower) biodiversity? reduced biodiversity
30
How is a cactus adapted to survive in a hot, dry desert climate?
31
Cactus are able to store water to last through droughts. They have shallow roots. They also have spines (leaves) to keep animals form chewing on them.
32
What type of organism will a pioneer species most likely be? (producer, consumer or decomposer)
33
What type of organism will a pioneer species most likely be? (producer, consumer or decomposer) Producer
34
What type of adaptations allowed these marine iguanas to swim in the water to eat alga, and cling to rocks withstanding waves?
35
What type of adaptation allowed these marine iguanas to swim in the water to eat alga, and cling to rocks withstanding waves? Natural Selection !
36
What type of adaptation allowed these marine iguanas to swim in the water to eat alga, and cling to rocks withstanding waves? Natural Selection !
37
What type of adaptation allowed these marine iguanas to swim in the water to eat alga, and cling to rocks withstanding waves? Natural Selection !
38
What is it called when people breed animals (like dogs) to show specific traits or qualities?
39
Selective breeding (which is NOT natural selection!)
40
You have light and dark colored moths. The trees are becoming dark colored because of pollution. Which moth is more likely to survive?
41
You have light and dark colored moths. The trees are becoming dark colored because of pollution. Which moth is more likely to survive? -Dark colored moths because the trees are covered in suit (black dust)
42
Describe the saying “survival of the fittest”
43
Animals with stronger traits have a easier time getting food, mates, and shelter. In turn they get to live longer and reproduce more. The “strong” traits get passed down while “weak” traits eventually fade away.
44
What do scientists use to help them determine classification of organisms?
45
Dichotomous keys
46
Gills, Xylem, Bones, and a Cow’s 4 part stomach are examples of
47
Gills, Xylem, Bones, and a Cow’s 4 part stomach are examples of Internal Adaptations
48
Know how to use dichotomous keys for Plants and Insects!
49
What happens to an ecosystem if you take out one of the consumers from the middle of a food web?
50
Know biome, habitat, and microhabitat. Be able to give examples of each one.
51
Make sure that you read every question CAREFULLY and to use your test taking strategies.
