Week 33 Ecology and Food Webs


Monday May 4 2013
QFD: Of all human powers operating on the affairs of mankind, none is greater than that of competition. Henry Clay
?FD: Name 2 carnivores, 1 producer and 1 decomposer in your food web
Objective: BSS 6f. Students know at each link in a food web some energy is stored in newly made structures but much energy is dissipated into the environment as heat. This dissipation may be represented in an energy pyramid.
Student will:
Differentiate between Mutualism, Commensalism, and parasitism
Explain the similarities and differences between autotrophs and the various types of heterotrophs
Interpret the correct way to answer questions on the handout starvation v Predation
Demonstrate the ability to read and select the main ideas using Cornell note taking techniques
1) Read pg 15 symbiosis through- 18
5) Cornell notes
HW: Define the following words in your notebook:
1) autotroph 2) heterotroph 3) herbivore 4) carnivore 5) omnivore 6) Detritivores 7) Food chain 8) Food web 9) biomass 10) biodiversity 11) habitat fragmentation 12) invasive species 13) producers 14) consumers 15) decomposers 16) chemosynthesis 17) photosynthesis 18)

QFD: Success is not a journey, it is a destination – Arthur Ashe
?FD: Differentiate between mutualism and commensalism
Objective:BSS 6f. Students know at each link in a food web some energy is stored in newly made structures but much energy is dissipated into the environment as heat. This dissipation may be represented in an energy pyramid.
Student will:
Identify the differences between a food chain and a food web
Interpret a Food Web by creating a Tree concept map
Compare and contrast the energy pyramid and the biomass pyramid

2) draw color and label a food web that incorporates your endangered species ( make sure your drawing is large but can be cut out and placed into your notebook

Needs to include : 7 animals and 2 plants , and label each according to food type and energy type ex heterotroph , primary consumer, herbivore .

QFD: He who is drowned is not troubled by the rain. Chinese Proverb
?FD: How much energy is lost between each trophic level?
Objective: BSS 6f. Students know at each link in a food web some energy is stored in newly made structures but much energy is dissipated into the environment as heat. This dissipation may be represented in an energy pyramid.

1) food web due

A great diversity of species
B a high birth rate
C a small population
D little or no competition

2 Besides habitat fragmentation, pollution and habitat loss, __________ can affect biodiversity by taking over niches of existing species and eventually replacing them.
A biogenesis
B abiotic factors
C Exotic or invasive species
D native species

3 Which of the following statements is true concerning biodiversity?
A Biodiversity is the lack of a diversity of species in an area.
B Biodiversity is the diversity of species in an area, which makes an ecosystem better prepared for major changes.
C Biodiversity is the diversity of species in an area, which leaves an ecosystem ill equipped to handle major changes.
D None of the above

4 The number of different species that live in a certain area is the most common measure of __________.
A biodiversity
B ecosystems
C food webs
D habitats

5 The biggest threat to biodiversity is __________.

B climate change
C deforestation
D habitat loss

7 If the biodiversity of an ecosystem is increased, the ecosystem will become __________.
A more stable
B less stable
C less resilient
D more resistant to evolution

8 Biodiversity can be altered by __________.
A unexpected changes in the climate of an ecosystem
B a fire in the ecosystem
C a flood in the ecosystem
D All of the above

9 A large number of individuals in a single species of desert tortoise die following a severe drought in the ecosystem. Which of the following MOST accurately describes the overall effect on the ecosystem?
A total tortoise population number will decrease, biodiversity will stay the same
B total tortoise population number will decrease, biodiversity will increase
C total tortoise population number will increase, biodiversity will stay the same
D total tortoise population number will increase, biodiversity will increase

10 Which of the following is MOST likely to cause a decrease in biodiversity?
A an immigration of species from another ecosystem
B a decrease in the total population of an ecosystem
C an increase in the total population of an ecosystem

11 The act of one organism consuming another for food is called:
A competition
B predation
C starvation
D digestion

12 Two organisms that live together in close association is called:
A) mutualism
B commensalisms
C parasitism
D symbiosis

13 When one organism benefits from harming another organism it is:

EC** Explain why only 10% of the energy is available for the next trophic level in an ecological pyramid
Thursday May 7 2013
QFD: Observations always involve theory. ~Edwin Hubble
?fd: Did you get 70% or greater right on the quiz? why or why, not explain
Objective:BSS 6f. Students know at each link in a food web some energy is stored in newly made structures but much energy is dissipated into the environment as heat. This dissipation may be represented in an energy pyramid

  1. Hey Borden did you say we’re doing the food web tomorrow or that it’s due tomorrow?

  2. Are we taking that quiz tomorrow?

  3. Have you fed the fish?

    • No I didn’t the food is in the drawer , thank you so much just give them a pinch the white things also feed them …
