Terms in this set (18)
1. Understand a food web and what is at each trophic level. Be able to name each trophic level.
Primary producer, primary consumer, secondary consumer, tertiary consumer, decomposer
2. What is the difference between primary and secondary succession?
primary succession- where the ground is not there in the first place or maybe the ground was there but no soil (mostly where the soil was brought from a different place)
Secondary succession- where there was soil and land in the first place but the land was damaged by fire, deforestation, floods, ect.
3. Describe survivorship curves
survivorship curves are graphs showing the number or proportion of biotic factors living to each age for a peticular species or group
Parental involvement helps to survive(e.g. males or females)
4. Describe and draw boom-bust evolution.
pred. and prey relationship shows a lag time for other species adjustment to a species population change (Cannot add picture on quizlet.com)
5. What is the difference between K and J-selection species?
K-selected species possess relatively stable populations and tend to produce relatively low numbers of offspring; however, individual offspring tend to be quite large in comparison
6. List examples of biotic and abiotic factors.
Abiotic Examples: Wind ,Soil ,Water ,Sunlight ,Nitrogen
Biotic Examples: bacteria, tree, flower, deer, and fish
7. What is the difference between species richness and species abundance?
species diversity- species richness and relative. Species diversity is determined not only by the number of species within a biological community
species richness—but also by the relative abundance of individuals in that community
8. What are the effects of the Law of Conservation of Matter and the Second Law of
energy is either given off or obtained, the entropy will always be positive
9. Biological magnification - which animal would have the most concentration of a toxic substance
- one at the top of the food chain or bottom and why?
the one at the bottom because only about 10% of the toxic substance is being passes along so the concentration become weaker and weaker as the food chain goes up
10. What causes acid rain and what are the details of its impact?
Acid rain is caused when chemical reactions take place due to chemicals such as sulfur dioxide or nitrogen oxides are polluted into the air the chemicals dissolve in the water in the atmosphere and soon the "acid" precipitates. It causes damage to crops and soil where ever it hits
11. Know the carbon, nitrogen, water cycle. Write the steps of each but also write the details of the
source of each step
Carbon- Carbon enters the atmosphere as carbon dioxide from respiration and combustion. Carbon dioxide is absorbed by producers to make carbohydrates in photosynthesis. Animals feed on the plant passing the carbon compounds along the food chain.
Nitrogen- Nitrogen Cycle. Step 1- Nitrogen Fixation- Special bacteria convert the nitrogen gas (N2 ) to ammonia (NH3) which the plants can use. Step 2- Nitrification- Nitrification is the process which converts the ammonia into nitrite ions which the plants can take in as nutrients.
Water- evaporation (and transpiration), condensation, precipitation, collection
12. Describe all details related to an exponential growth model.
it is a J curve when there is an unlimited amt. of recources
13. Describe all details related to a logistic growth model.
it is an S curve when there is a limited amt. of recources
14. Identify and describe the parts of the aquatic environment.
photic zone- upper rigion, light penetration
aphotic zone- lower region, no light penetration
benthic zone- bottom of ocean
abyss- deepest part of benthic zone
intertidal zone-harsh environment because of tides
coral reef- rich in bio-diversity because of light presence
15. Describe the 10% rule in regards to the energy pyramid (describing each level in detail of the
only 10% of all energy is passed on to the next level of the food chain ex. 9000J - 900J
16. Name and describe each aquatic biomes and the details.
ponds lakes- Limited species diversity
streams rivers- you need directions little water flow starting in one place and ending in the ocean
wetlands- marshes and swamps of the most diverse, mostly have reptiles
oceans- largest biome, covers three fourths of earths surface
estuaries- where streams merge with ocean
17. Why is the tropical rainforest so ideal?
The hot and humid conditions make tropical rainforests an ideal environment for bacteria and other microorganisms. Because these organisms remain active throughout the year, they quickly decompose matter on the forest floor, also the nitrogen in the soil is almost always naturally prsesent
18. Be able to describe the biomes in relation to their location geographically (latitude)
