The arrows in a food chain show: a Who eats who b Heat energy being lost c The movement of energy between organisms d The route of food to the shops

Answers

Answer:

c The movement of energy between organisms

Explanation:

Pyramid of energy is a model used to depict the flow of energy from one trophic level or feeding level to the next in an ecosystem. It's a diagram that compares the energy used by organisms at each trophic level of the food chain. The pyramid of energy must never be inverted or turned upside down.

The units used in the construction of pyramids of energy is kilocalories (kcal) or energy per area per time (Jm-²year-¹).

This ultimately implies that, the arrows in a food chain show the movement of energy between organisms such as from producers which are autotrophs or self-feeders such as plants to the tertiary consumers.

Furthermore, a list of the types of organisms in an eco pyramid are;

I. Producers: these are autotrophs or self-feeders such as plants.

II. Primary consumers: these are herbivores that typically feed on plants such as a goat or deer.

III. Secondary consumers: these consists of carnivores that typically feed or eat flesh such as lion, tiger, cheetah, etc.

IV. Tertiary consumers: these are higher predators such as humans that aren't normally fed on by other organisms in the ecosystem.

Answer: The arrows in a food chain show (The movement of energy between organisms). The correct option is C.

Explanation:

In an ecosystem, a food chain shows the transfer of energy and nutrients ( food) from organisms to organisms in a feeding pathway. Instead of giving functional group names such as primary producer, primary consumer and so on, in a good chain, the organism at each step is identified. Thus,

Grass-------> Zebra ---------> lion

(Primary (Primary ( secondary

producer). consumer) consumer)

this is an example of a simple food chain in a grassland ecosystem. This ARROWS represented above shows the direction of energy flow through an ecosystem.

Furthermore, the grass traps solar energy and stores it as chemical energy in the food made during photosynthesis. When eaten by Zebra, which is the primary consumer, the energy stored in the grass is transferred to the consumer. This transfer is inefficient as some of the stored chemical energy is lost as heat. When the zebra is eaten by a Lion,which is the secondary consumer.

The dichotomous key below provides a way to classify some animals into groups according to their physical characteristics. The key can be used to classify each of the four animals represented below. Which answer choice shows the correct classification group for each animal? 1. Wasp = group D; Ant = group D; Tiger = group A; Bird = group B 2. Wasp = group B; Ant = group A; Tiger = group D; Bird = group C 3. Wasp = group B; Ant = group D; Tiger = group A; Bird = group C 4. Wasp = group D; Ant = group A; Tiger = group A; Bird = group B

Answers

Complete question:

The dichotomous key below provides a way to  classify some animals into groups according to their physical characteristics.

Dichotomous Key

        I wings------------------go to II

          no wings------------- group A

       II feathers---------------group B

          no feathers----------go to III

      III two legs------------- group C

          six legs---------------group D

The key can be used to classify each of the four  animals represented below ⇒ wasp, ant, tiger, bird

Which row in the chart shows the correct  classification group for each animal?

Row    Wasp           Ant           Tiger          Bird

 (1)      group D    group D    group A     group B

 (2)     group B    group A     group D     group C

 (3)     group B     group D     group A    group C

 (4)     group D     group A     group A     group B

Answer:

Row    Wasp           Ant           Tiger          Bird

(4)     group D     group A     group A     group B

Group A: Tiger and Ant → They do not have wingsGroup B: Bird → It has wings and feathersGroup D: Wasp → It has wings, does not have feathers, and has six legs

Explanation:

When analyzing a dichotomous key, you just need to pay attention to the given descriptions and carefully observe the organisms you have.

The key describes specific morphological traits of each organism that are useful to differentiate it from other organisms. So all you need to do is to follow the instructions given in each step, and the key will guide you directly to the answer.  

In the exposed example you have four organisms: wasp, ant, tiger, bird

The provided key gives you three steps: I, II, III.

Step I:

wings------------------go to II

no wings------------- group A

Here the key tells you to separate, from your group of organisms, the ones that have wings from the ones that do not have wings.

wasp and bird have wings → So you need to go to step IItiger and ant do not have wings → So they belong to Group A

Step II:

feathers---------------group B

no feathers----------go to III

Now you only need to consider the bird and the wasp, which are the two organisms that have wings.

Here the key tells you to separate the one that has feathers from the one that does not have feathers.

Bird has feathers → So it belongs to the group BThe Wasp does not have feathers → So you need to go to step III

Step III:

two legs------------- group C

six legs---------------group D

In this last step, the key takes you to two possible groups. But you only have one left organisms, which is the wasp. So what you need to do is to observe how many legs your wasp has. It is an insect, so it has six legs. The wasp belongs to Group D.

You do not have any organism that belongs to group C.

To sum up, according to the given information you could group the group of organisms as follows:

Group A: Tiger and Ant → They do not have wingsGroup B: Bird → It has wings and feathersGroup D: Wasp → It has wings, does not have feathers, and has six legs
