If you looked at Alphabet Soup, you see the alphabet represented... but if you looked at a Beef Stew, what would you see?
body tissues
starch and sugars
ribosomes and ER
organelles
Which of the following does NOT belong?
Which of these is unicellular organisms?
Which is a correct description of how Multicellular organisms are different than Unicellular?
Multi requires energy to survive
DNA is only found in multi
Photosynthesis plays a large role in multi
Multi have connected cells that have special jobs
Animal cells are similar and different to plant cells... but what allows materials in and out of an animal cell?
vacuoles
vesicles
cell wall
cell membrane
All living organisms have limbs.
All organisms produce their own food and energy.
All organisms breathe air.
All living things are made of cells, according to Cell Theory.
Why do both plant and animal cells have a nucleus?
Both need a recycling center.
Both need a control center.
Both do not have a nucleus.
Both need a place to store energy.
Why do cells need mitochondria?
photosynthesis
eliminate waste
food production
energy production
What are the differences between plant and animal cells?
cell wall
ribosomes
ER
chloroplast
vacuole size
Which would best represent the cell membrane?
strainer
brick wall
balloon
jacket
Which of the following are SIMILARITIES between uni-cellular and multi-cellular organisms?
can be part of plants and animals
have a nucleus and chloroplasts
specialized
get rid of waste and reproduce cells
have a flagella
How are uni-cellular and multi-cellular organisms DIFFERENT?
uni carries out all the processes while multi are specialized
uni are single cells responsible for all life processes
multi-cellular have a longer life span
uni and multi both allow cells to share workloads
Invasive species can be compared to WEEDS in a flowerbed. What can be considered the reason that the native plants would die while the weeds live!?
overwatering
overcrowding
parasite
If there was not enough water, or not enough soil, or even not enough sunlight for plants to survive... these things would be considered
parasitism
commensalism
limiting factors
carrying capacity
If an environment, ecosystem, or habitat is maxed out with the resources it can provide... it has reached its
limiting factors
carrying capacity
mutualism ability
parasitic capacity
Recall the Energy Pyramid LAB we completed. The different levels recovered or changed at different rates. Why does it take longer to build from the bottom back up?
herbivores eat producers too quickly
it supports the entire pyramid and it is harder for them to recover
carnivores eat each other first and then focus on the producers
only one level of the pyramid is affected by a change, not all of them
Why would a consumer begin eating another food source?
easier prey
original food source had decreased due to disease or human hunting/fishing
no reason, just bored
original food source lost nutritional value
prey became bigger and a harder challenge to capture
Arrows in a food chain or web represent
single relationships between predators and prey
the flow of energy in an ecosystem
how animals move and migrate
the smallest to largest animals
Kelp shelter plankton. What would this symbiotic relationship represent?
mutualism
commensalism
predation
parasitism
Fish are the main food source of Seals and Sea Lions, and they eat other organisms as well. What would this relationship represent?
mutualism
commensalism
predation
parasitism
Pilot fish travel with sharks and whales to eat their leftovers. What would this symbiotic relationship represent?
mutualism
commensalism
predation
parasitism
What all would result in an Ocean food web (otters, seals, sea lions, killer whales, kelp, etc.) if commercial (large-scale) fishing was reduced?
more fish = more food for seals, sea lions (inc population)
more fish = more killer whales
more seals, sea lions = less otters for killer whales
more seals, sea lions = killer whales eating less otters
If a predator has 2 main types of prey, and one prey (#1) population increases, the predator will most likely eat less of the other prey (#2).
If a predator has 2 main types of prey, and one prey (#1) population decreases, the predator will most likely
eat more of Prey #1
eat more of Prey #2
Can land and water ecosystems overlap and SHARE the flow of energy?
Yes! You dork!
No! You crazy!
If a prey were to disappear, whether by migration or extinction, what would their predator have to do to survive?
try to get to the best temperate part of the forest
compete with other species
be sure to become the dominant sex
go to the most humid part of the forest
Which of the following could be considered a decomposer that breaks down the dead wood into nutrients that make the soil more fertile?
fungus
caterpillars
mushrooms
worms
butterflies
What would be a possible impact by removing decomposers and dead material from a forest?
increase chances that herbivores will take over
decrease soil fertility and nutrients
decrease vegetation and photosynthesis
increase forest fires
What could be a possible reason that a species' population would decrease even when at carrying capacity?
reproduction increased
competition decreased
predation decreased
competition increased
How do abiotic factors play a role in a forest community?
increased rain increases mosquitoes and dragonflies
invasive species aggressively decrease native plants
a fungus infects the ecosystem and decreases herbivores
increases in fly populations create increases in bird populations
Which of these would be considered abiotic parts of an ecosystem?
A tree by itself can be like an ecosystem. What does it use and process through its roots, trunk, and leaves?
the roots pull water from the soil for nutrients
some water is released as water vapor
carbon dioxide is taken in, processed, and released as oxygen
decomposers decrease nutrients available for the trees
animals that burrow beneath the roots take away from the food available to trees
Which of the following are considered mutualistic relationships?
Which pictures would NOT be the best to represent molecules of carbon dioxide, water, or another group of bonded atoms?
All substances change their phase BEFORE their temperature can increase at certain stages (ex: solid, liquid, gas).
Temperature and movement of molecules BOTH increase, or BOTH decrease together
Which of the following animals have increased in extinction danger as human populations have increased... they have a DIRECT RELATIONSHIP?
What are the three main natural resources humans consume from Earth, and it it causes lots of pollution and danger to animals!?
coal
corn
oil
natural gas
sunlight
