RELATIONSHIPS IN ECOSYSTEMS

[blank_start]Living things[blank_end] are affected by different [blank_start]factors[blank_end] in the enviroment. Some factors have a [blank_start]greater[blank_end] influence on living things.

What does it determine which living things can survive in a particular place?

Can living things modify the enviroment?

The [blank_start]components[blank_end] of an ecosystem are in [blank_start]balance[blank_end] with each other. This balance can easily be affected by [blank_start]changes[blank_end].

Are anyone of these answers changes in an ecosystem? Check out the true ecosystem's changes (and discard factors)

What do these main factors affect to? [blank_start]TERRESTRIAL[blank_end] ecosystems: temperature, humidity, type of soil and light [blank_start]AQUATIC[blank_end] ecosystems: temperature, water currents, light and salt content

Select factors (and not changes) that affect enviroments

An area where a living thing lives and can find everything it needs is its [blank_start]habitat[blank_end].

Link the right type of ecosystems [blank_start]TERRESTRIAL[blank_end] - Forests or deserts [blank_start]AQUATIC[blank_end] - Lagoons or rivers

All living things need food to survive. Depending on how they obtain their food, they can be classified as ... (in plural please :-)) 1. P[blank_start]roducers[blank_end] 2. C[blank_start]onsumers[blank_end] 3. S[blank_start]cavengers[blank_end] and d[blank_start]ecomposers[blank_end]

How many type of consumers are there?

[blank_start]Producers[blank_end] are living things that make their own food [blank_start]Consumers[blank_end] are living things that obtain their food from other living things [blank_start]Scavengers[blank_end] feed on the remains of dead animals [blank_start]Decomposers[blank_end] break down dead animal and plant material

What kind of living things are these depending on their nutrition?

Species adapt to their enviroment. What does ADAPTATION allow living things to?

Plants with small leaves in dry climates, Polar bears with paws to help them to swim,... ... are examples of:

Select the right types of living things that feed as DECOMPOSERS

Is this a food web or a food chain?

Which choice is right?

Food [blank_start]chains[blank_end] show how living things [blank_start]feed[blank_end] on other living things in a ecosystem.

Which choices are true? (there's more than one)

The relationship between two species ... ... when both benefit is [blank_start]MUTUALISM[blank_end] ...when one benefits and the other remains unaffected is [blank_start]COMMENSALISM[blank_end] ... when one benefits while the other suffers is [blank_start]PARASITISM[blank_end] ... when both have the same needs is [blank_start]COMPETITION[blank_end]

Drag the right type of relationship depending on the faces of each one
