ECOSYSTEM WORKSHEET
Part 1: General Description
1.- Ecosystem type (terrestrial, aquatic, salty water, fresh water)
2.- Position. Locate it:
- Latitude/Longitude
- On an local map
- In relation to the school (distance)
- In aerial photos
3.- Production of a Ecosystem approximate map, showing
- Orientation
- Remarkable structures, both natural and artificial such as: rock formation, mountains and buildings nearby, forests or tree groups.
- Human action: positive and negative
- Approximate area
4.- Take pictures of the area to study. Try to show pollution remains and state of conservation, human action…
Part 2: Analysis of Abiotic factors
1.- Production of a climograph of the area to study.
2.- Data taking (atmospheric conditions):
- Air, ground and water temperature (in case of aquatic medium)
- Clouds: Type and cover, wind: speed and direction, environmental humidity
3. Identification and description of the analyzed rocks. Pictures for the blog
4.-Study of the ground:
- Terrestrial ecosystem:
-
“In situ” study of the ground and its features with magnifying glasses to identify the size of its particles (gravel, sand, clay....)
-
Afterwards, classification of the organic and inorganic components in the lab by using binocular magnifying glasses
- Marine or lake/river ecosystem;
-
Study and description of its particles (sand, stilt).
-
Classification in the lab according to size shape and colour together with their origin (organic and inorganic)
- Production of a granulometry of the samples in the lab
Part 3: Study of Biotic factors
1.- Producers
- Moss, ferns and lichens:
-
Look for them and show their position on the map, pointing out their orientation and cover. Description and afterwards classification in the lab.
-
Search for information, in the classroom, about the lichens, as a bio indicator
- Herbaceus plants:
- Tree specimens:
- Algae (in aquatic ecosystems):
-
Describe 2 of each type (green, brown or red).
-
Prepare an ecosystem profile and point out their position.
-
Take photos and samples (if possible), to later classify them in the lab
-
Produce a small algae guide
2.- Consumers/Animals:
- Invertebrates:
-
Look for 2 specimens in each group, take photos and videos showing their movements
-
Anatomic description of each one
-
Sort out samples (shells)
-Vertebrates:
-
Identify and look for traces (using simple guides)
-
Production of info cards: Usual and scientific name, features, way of living
**Watch out! Neither hurt the specimen nor damage its habitat.
3.- Decomposers:
- Fungi :
-
Samples picking up, description and photo taking.
-
Classification in the lab.
-
Search information about the role of fungi in the ecosystems and the use of fungi in the food industry, human diet...
Part 4: Relationship and adjustment to the habitat
- Production of trophic chains with the found living creatures and creation of a possible food web with them.
- Find information about inter specific relationships such as mutual, symbiosis, parasitism.....you can find in your ecosystem. Description of them.
- Look for examples of adjustment to the habitat among the studied species, such as humidity, saltiness, wind...
Part 5: Invasive species
- Research about the presence of invasive species in the area, and look for information about the potential consequences of their presence together with the existence of eradication programmes
- Try to find, at least, two examples of those species, describe them, and tell about their origin and their possible effects in the ecosystem.
Part 6: Pollution and Changes study
- Waste collection during visit and afterwards classification at school
- Plastic: Pick up samples and classification in the lab. Research about the effects of the plastic in the aquatic ecosystems.
-Picture collecting of the area in the last decades, to produce a small work about its evolution. Critical analysis and approach of the possible corrective measures
