faust18 [17]

Answer: D) The lizard and the snake are secondary consumers.

Explanation:

Producers are organisms that, simply put, produce their own food. All photosynthesizing plants are considered to be producers. Animals cannot be producers.

Primary consumers eat producers.

Secondary consumers eat primary consumers.

Tertiary consumers eat secondary consumers, and so on.

The lizard eats a fly, which is a primary consumer. This makes the lizard a secondary consumer.

The snake eats a mouse, which is a primary consumer. This makes the snake a secondary consumer.

Which statement best describes the evolutionary significance of mutualism?
krok68 [10]

Answer:

C) Interaction increases the survival and reproductive rates of mutualistic species.

Explanation:

A) Mutualism offer more biodiversity to a community.

    Biodiversity is the different species living in one environment. Since mutualism is only involving two species, it wouldn't increase the biodiversity of one ecosystem, making it incorrect.

B) Individuals partaking in a mutualistic relationship relationship are more resistant to parasites.

    Mutualism is only benefiting two species, not their immunity to diseases and parasites. These two have no correlation with each other, making it incorrect.

D) Mutualistic interaction lessens competition in communities where it is present.

    Since mutualism is only benefiting two species, they have no correlation since the relationship doesn't affect the different species in the environment.

E) Mutualistic relationships allow organisms to synthesize and use energy more efficiently.

    Although there could be some relationships involving energy transfer between the species, that would sound more like commensalism or even paratsitism if you think about it. However, it is very uncommon and usually energy has no relationship with species relationships, making it incorrect.

Hope this helps! My deepest apologies if I got in incorrect!

what happens to the two small balloons inside as you pull down the big balloon at the bottom of the model?​
xeze [42]

Answer:

The lower pressure balloon will expand. Figure 2 (above left) shows a typical initial configuration: the smaller balloon has the higher pressure. So, when the valve is opened, the smaller balloon pushes air into the larger balloon. It becomes smaller, and the larger balloon becomes larger.

Hope this is helps out

Some please help me with the problem at certain times,the stomata on the tree leaves close. What environmental stimulus might ca
Lisa [10]

Stomata close when the vacuoles in the guard cells fill with water and the cells become turgid.  The environmental stimulus that causes this response is the change from light to dark.  During the day, heat from the sun causes evaporation in the leaves, which leads to water loss from the leaves, by way of the stomata, in a process known as transpiration.  At night, the absence of the sun's heat slows the rate of evaporation, causing the vacuoles in the guard cells to fill with water by way of osmosis, causing the guard cells to become turgid and seal off the stomata.
