Question

5. Using organisms from the food web for your ecosystem, describe examples of the following: a. A symbiotic relationship: b. A predator-prey relationship: c. Competition: d. Limiting factors that may affect the survival of the organisms: e. Density dependent and independent factors that may affect the survival of the organisms:Ponds are a type of freshwater ecosystem that has shallow and slow-moving water (is lentic), and, because it's shallow, light can reach the bottom of it.Some organisms that we can find living in a pond are the following:Water liliesFrogsTurtlesFishGeeseDragonfliesAlgaeCyanobacteriaDucksWater snailDuck potatoEarthwormsMosquitosPond skaterNewtsMosquito fern/fairy mossDuckweedsWatersnakeSalamandersWater beetleProducers: water lilies, algae, cyanobacteria, duck potato, mosquito fern/fairy moss, and duckweedsPrimary Consumers: ducks, geese, fish, water snails, turtles, earthworms, frogs, pond skaters, and water beetles.Secondary and tertiary consumers: ducks, geese, fish, frogs, dragonflies, water beetles, newts, water snakes, and salamanders. 4. Producers include water lilies and duck potato. Consumers include ducks, frogs, pond skaters, water beetles, water snails, fish, water beetles, water scorpion, dragonflies, mosquito, duckling, leech, newt, and tadpole.

Answer 1

Step 1.

Outline the food web given by the question:

Producers: water lilies, algae, cyanobacteria, duck potato, fern/fairy moss, and duckweeds;

Primary Consumers: ducks, geese, fish, water snails, turtles, earthworms, frogs, pond skaters, and water beetles;

Secondary and tertiary consumers: ducks, geese, fish, frogs, dragonflies, water beetles, newts, water snakes, and salamanders.

Step 2.

a. A symbiotic relationship is a close ecological relationshp between two species. being a exmaple of a symbiotic relationship with the food web present in the question the relation between cyanobacteria and algae, both can work together to make photosynthesis since the species are bacteria with algae traits;

b. The Ducks in the food chain are predators, while the fish the prey, being a relationship of predator-prey inside the ecosystem used as example;

c. The frogs and dragonflies have a competition to eat the mosquitos in the pond;

d. Some of the limiting factors for that ecosystem are the water temperature and oxygen, the number of producers, and the human activities that can affect the body of water in the pond (pollution);

e. The dependent factor are related to biotic factors such as food, predation, disease, migration, and parasitism, while the independent factors are related to environment (abiotic) such as climate and degradation of the water body.
