Wetland
What is a wetland?
Wetlands are areas that are too wet to be considered land but not wet enough to be considered lakes.
What is an ecosystem?
An ecosystem is the interaction of living and non-living things in the environment.
Snail belongs to which of the following groups:
a. Mammal
b. Reptails
c. Mollusk
d. crustacean
c. Mollusk
What is physical adaptation?
A modification to the structure of a living things' body to help it survive
What is a food chain?
What is a food web?
Food chain: to show the connection and interaction between organisms that feed on each other, transferring energy and nutrients
Food web: also show how organism interact, but they include different food chain
What are the two main categories of wetlands, and what makes them different from each other?
Peatland and non-peatland. They are different because peatlands contain peat, and non-peatlands don't have peat.
Peat is made of decomposed plants. They produce acid in the water
What is biotic and abiotic things?
Provide 2 examples of biotic and abiotic things.
Abiotic: Non-living
Biotic: animals, plants, bacteria etc
Abiotic: water, sand, sunlight, rock etc
Provide examples of a decomposer
worm
mushroom
insect
fungi
bacteria
What is behavioural adaptation?
A modification to way a living thing acts to help it survive
What is the role of a grasshopper in the food chain?
primary consumer
5 main types of wetlands can be found in Alberta. They are grouped under peatland and non-peatland. Name all 5 wetlands and identify whether they are in the peatland or non-peatland group.
Peatland: Bog (muskeg) & fen
Non-peatlands: Marsh, shallow water (ponds and potholes) and swamp
All organisms in an ecosystem need energy to live. Organisms can be grouped by how they get energy. Organisms in an ecosystem are mainly grouped as......
HINT:
1. an organism that can produce its own food
2. an organism relies on eating other small organisms
3. an organism that breaks down dead materials.
Producer, consumer and decomposer
The life cycle of a human or duck is an example of:
a. simple life cycle
b. incomplete metamorphosis
c. complete metamorphosis
a. simple life cycle
(Metamorphosis mostly are for insect)
Bear hibernation and bird migration are example of which types of adaptation?
Behavioural adaptation
Plants--> grasshopper --> rats --> snake
What is the role of a snake in this food chain?
Tertiary consumer
Identify the following types of wetland:
They have slow-moving water. Soft-stemmed plants and long roots that allow plants and leaves to stay out of water.
Water comes from groundwater and precipitation.
Marsh
In lesson, we learned that trees are classified into 2 categories: Coniferous and Deciduous.
Which category represents trees that will keep their leaves all year round?
Coniferous
A life cycle of a grasshopper contain 3 stages:
egg--> Larva/Nymph --> Adult
This is an example of :
a. simple life cycle
b. incomplete metamorphosis
c. complete metamorphosis
b. incomplete metamorphosis
( only 3 stages and also without pupa --> incomplete)
Water lilies have long stems and big leaves to help them stay above water and absorb sunlight. This is an example of which type of adaption?
Physical adaptation
Plants--> grasshopper --> rats --> snake
Explain what would happen to the snake if it dies. HINT: decomposer
When the snake dies, fungi and other bacteria will break down its body and turn them into nutrients.
Identify the following wetland:
Pond or potholes. It has two zones; the emergent zone and the submerging zone.
Emergent zone: all plants that grow outside of water
Submerging zone: all plants that grow underwater
Shallow water
Consumers can also be grouped into 3 categories: herbivores, omnivores and carnivores
Explain each category
Herbivores: plant eater
Omnivores: Plant and meat eater
Carnivores: meat eater
what are the characteristics of a complete metamorphosis?
- 4 stages
egg, larva,pupa and adult
-Life cycle of an insect
Identity the adaptation of a mosquito
Mouth that is like a needle to pierce skin and suck up blood (physical adaptation)
Plants--> grasshopper --> rats --> snake
Extreme weather pattern causes difficulties for plants to grow.
Explain what would happen to the food chain.
The amount of energy that is transferred within the food chain will be greatly reduced. The population of grasshoppers, rats, and snakes will be reduced and affected.
The number of grasshoppers will be reduced due to the limited food available for them to consume. The rat population will also decrease due to the reduced food source. Eventually, this will cause snakes to have fewer rats to eat, leading to some snakes not surviving and resulting in a decrease in the snake population.
